Introduction

Have you ever noticed that the modern church is addicted to the big, to the bold, to the spectacular. If it doesn’t draw crowds, if it doesn’t create excitement or feel emotionally powerful, many assume it cannot be spiritually significant. We hear the buzz words constantly, radical, revolutionary, relevant. And gradually, the ordinary faithfulness begins to fade as something that is rather spiritually inferior. Attending church regularly, loving your spouse, raising your children in the fear of the Lord, working honestly, and participating in the life of the church.

But what if God delights… To do the extraordinary through the ordinary? What if lasting Christian growth is usually slow, steady, and deeply ordinary? In a restless age, obsessed with spectacle, ordinary Christian faithfulness may actually be the most counter-cultural thing to do.

And that’s exactly what we see in Hebrews 3, verses 12 to 15. It calls us to not celebrity Christianity, not spiritual spectacle, but a faithful church helping one another keep looking to Christ all the way to the end. So let’s consider this main idea. The faithful church helps one another keep looking to Christ all the way to the end.

The author of Hebrews unfolds this passage through three movements.

The first is the faithful church carefully watches over one another’s souls. There’s a danger here. We’re going to explore that.

The second… The faithful church encourages one another to fight sin and keep looking to Christ. That’s our duty.

And then the last, the third, the faithful church helps one another persevere as those united to Christ. And that is our hope.

So we’ve got a danger, a duty, and a hope.

Point 1: The Faithful Church Carefully Watches Over One Another’s Souls

The Danger — Hebrews 3:12

Most Christians… Don’t abandon the faith all at once. It drifts slowly through isolation and unbelief begins to harden their hearts. But according to Hebrews, one of the primary ways God preserves His people is through the faithful care of His church. That’s in verse 12. We’ll read that again.

Hebrews 3. Take care… Brothers, lest there be in any of you an evil, unbelieving heart leading you to fall away from the living God.

Take care. It’s not some polite goodbye. It’s a spiritual warning. It means take heed, beware, pay close attention. The Holy Spirit is sounding an alarm. So the question is, are you listening?

Notice the author is saying brothers. Not holy brothers, as earlier in the chapter. The warning here is addressed to the visible church. You see, in every church there are true believers and those who merely profess faith outwardly. Jesus said, the wheat and weeds grow together until the end. One of the great dangers of church life is assumption. Assuming church attendance equals spiritual health. Assuming someone else will step in when we see that person struggling. Assuming that, man, this drift, this wandering, little bit here, little bit there, not so bad. But concern for souls is not the same thing as sinful worry. Worry changes nothing. Godly concern drives us into faithful action.

There’s the story of a man who joined a church because he loved the preaching. He sat in the same seat every Sunday. He sang loudly. He even served on occasion. Everyone assumed that he’s doing well. But over time, subtle changes began to take place. Well, he stopped going to church every Sunday. That’s a bit radical. Prayer became rare. Scripture was easily neglected. People in the church, they notice something’s wrong. I can sense it. I just don’t know what it is, but nobody said anything. Everybody else assumed someone else would step into his life. And then months passed. His heart grew colder. Sin became a little easier to justify. Church life became more of a chore than a joy. Eventually, he left his wife for another woman and completely abandoned the faith. And afterward, an elderly man quietly said with tears, we watched him slip away. Inch by inch. And nobody loved him enough to step into his life.

That’s why verse 12 is so urgent. Yeah, elders are called to shepherd the flock. But guess what? Soul care belongs to the entire church. We’re not to assume that everyone here today or not even here today is okay. Someone else will check on them. Someone else will do the work of the ministry. I’m just here to receive. We’re called to be different. We’re called to press in to one another’s lives. Even when it feels really uncomfortable. Why? Because it’s the loving thing to do.

Notice where the author places the danger here. You see it? It’s the heart. In other words, it’s the very thing that’s extremely easy to hide. I can’t see your heart right now. We can’t each other see our hearts. What you love most, what the desires that shape your life, man, they’re there. I just can’t see them. Spurgeon compared the heart to a pond freezing in winter. Slowly, almost unnoticed, until it becomes solid ice. Jeremiah 17.9 says, you know it, the heart is deceitful above all else. It’s desperately sick. Who can understand it? Guess what that means? None of us, none of us is beyond self-deception. The heart can quietly, ever so subtly, convince us a few little whispers. I don’t need the church. My sin isn’t that serious. I can handle this on my own.

That’s why faithful churches practice loving accountability. Honest soul care. Not suspicion-driven Christianity. Wondering what is that? Oh, did you hear? No. Love-driven faithfulness. Christian, no one is beyond drifting. But Christ is faithful. And therefore, we strive together to keep looking to Him. And it’s the job of the whole church to watch carefully over one another’s souls.

I’m convinced of this, that every member of the body has a role in this. Don’t assume that since Christ is faithful to save, and He is, that we need not be concerned about souls. Proverbs 11.30 says, he who wins souls is wise. Listen, it’s not simply about converting people. I got another one. Another one. It’s about skillfully and carefully pursuing souls for their good. It’s possible to stay very busy externally while drifting ever so slowly internally. But the Lord, He is more concerned about the heart than the head, you see.

It’s the elder who notices someone growing distant spiritually. It’s the member who sees her sister growing cold toward Christ spiritually. Scripture provides so many warnings for us. James says, whoever brings back a wandering sinner will save his soul from death. Jude says, we are to save others by snatching them out of the fire. Remember this, the Christian life, it’s not a passive one. Yeah, we trust that Christ will keep His sheep all the way until the end. But don’t you want to be part of that keeping process? Don’t you want the Lord to use you to rescue a wandering soul? Not to save them eternally, but to save them from destruction, from the fire. It’s the ordinary thing. It’s the everyday thing.

A heart that stops trusting Christ will eventually wander from Him. But the faithful church doesn’t assume that everything is okay. The faithful church lovingly presses in and asks those hard questions. You see, as believers, yeah, we serve the living God. But few things are sadder than watching someone slowly lose their tenderness toward Christ. And that’s why this sound doctrine matters so deeply. We want a foundation that lasts for generations. We don’t want our young people to drift from Christ as they get older. To go to college. Find something else. Because they didn’t have the foundation. Hebrews 2.3 says, how shall we escape when we neglect so great a salvation? It’s so easy to neglect. And the neglected one in the church easily justifies their departure. Oh, that church, they didn’t care about me. I’m a lot better off without the church. No. Dear Christian, your soul is in peril without the church. You need the church. I need the church.

I want it to be said of us that, oh, I saw the warnings but did nothing. We’re called to faithfulness, not perfection. We’re called to commit to the ordinary, to the long, to the often dull, daily grind of the Christian life. This is the faithful church that watches over one another’s souls carefully because spiritual drift, it rarely announces itself.

Point 2: The Faithful Church Encourages One Another to Fight Sin and Keep Looking to Christ

The Duty — Hebrews 3:13

So how do we… Actually help one another to persevere in the faith. What does this soul care look like in practice? Verse 13 now moves from warning to remedy, from danger to duty. The author shifts from take care, beware, to encourage one another daily. In other words, the church that is not only called to identify the drift, but it’s to actively help one another fight against it. And that leads us to point two. The faithful church encourages one another to fight sin. Better word is fight than turn away, because this is what we need to be doing. And keep looking to Christ. It’s verse 13.

But exhort one another every day, as long as it’s called today, that none of you may be hardened by the deceitfulness of sin.

Brothers and sisters, the Lord is encouraging us to exhortation mutually. It’s not just to encourage with positive affirmations. It carries with it strength, strength from the Word, through the power of the Spirit. So let me ask you, is the spiritual well-being of others important to you? Scripture is clear. It should be. In fact, much of Hebrews is exhortation. It’s comfort, growth, and guidance. But it’s also urgent. Romans 12.8 even lists exhortation as a spiritual gift. Barnabas was called the son of encouragement because he believed in the power of God’s grace. He stood by John Mark and the newly converted Paul when others wouldn’t do it. Exhortation is our Christian duty to one another. And it happens in the ordinary life of the church.

So how often then, you might ask, should this kind of encouragement happen? Is it reserved for the Lord’s Day? just on Sunday morning gathering? No! The author clearly says that we are to exhort one another every day. This is day after day after day. Ordinary faithfulness. Why is that so important? Well, we mentioned it already. My heart, your heart, easily hardened. Notice how the author, he presses the point. He says, do it every day as long as it’s called today. Every day is today. And Satan loves to convince us, oh, there’s always tomorrow. Tomorrow, I’ll repent. Tomorrow, I’ll encourage them. Tomorrow, I’ll get serious about prayer. But God calls us to faithfulness today. Give us today our daily bread. Christian, delayed obedience is one of Satan’s favorite tools.

We need encouragement today. It’s great to get God’s Word every day. To sit before His feet, open His Word, pour out your heart, read the Scriptures, meditate upon them, be filled up. It’s a wonderful thing. Do it every day. Yes. Spend that time. But there’s something so powerful about hearing and encouragement face to face. Yeah, texts and phone calls are helpful. But when you can look your brother in the eye, when can you encourage him with a word from God’s Word, when you can tell him, man, I know you’re struggling. You’ve just got to keep looking to the Lord. You point them to Christ. You don’t condemn them. You build them up. The Lord uses you by His Spirit. That’s a grace from God.

It’s all well and good, Pastor. But how do we know we’re doing this right? What does this encouragement look like? In other words, how do we know it’s effective? Well, that’s exactly what we’re seeing in verse 13. It’s the goal of a faithful church that none of us may be hardened by the deceitfulness of sin. Sin disguises its destruction. If we had seen it in its devastation beforehand, we would never, ever have chosen it. But sin comes on the scene, all dressed up fancy, making all these promises, telling you all the wonderful things it’s going to deliver. It tells us you’ll have joy. You’ll have peace, comfort, security. You don’t need Jesus. You don’t need the church. This is going to provide. I got something for you. We know that Satan comes as an angel of light, appealing to our sinful desires. Sin is seductive, but it’s ultimately empty because at its core, sin believes that Christ is not enough.

Oh, I did church on Sunday. Today’s my day. That’s right. My day. I get to do what I want on my day. You see, we naturally want to live on our own terms. Have our time. It’s me time. But independence from God is never freedom. It’s always slavery to sin.

I think about this story of a young man attending a small country church. Pastor started to notice that something had changed in his life. He was attending. He was smiling. But when it came to talking about spiritual things, for some reason, he became a little defensive. Eventually, the pastor found out that he was involved deeply in pornography and And what was worse is that nobody knew about it. He carefully kept it in the dark for years until one day the pastor asked him to go out for coffee and he finally said, brother, I’m concerned that your heart is growing cold toward Christ. Well, when he said that, the young man became irate. How dare you? How dare you judge me? But a few moments passed. There was this quietness. And finally, with tears in his eyes, he admitted, Pastor, I’ve been struggling with this addiction for years. I thought nobody knew. Nobody cared. And I hoped that nobody would find out.

But that very conversation was the turning point in his life. Didn’t happen overnight. But through regular, ordinary, accountability, confession, prayer, steady encouragement, that young man found freedom. And the Lord slowly restored him to that joy that he once had. Years later, that same young man said this, the most loving thing anyone ever did for me was to refuse to leave me alone in my sin. That’s exactly verse 13. Exhort at one another every day, then none of us will be hardened by the deceitfulness of sin.

Sin lies to us. It promises freedom, but it produces slavery. It offers comfort while quietly hardening the heart. So what’s the regular rhythm of the church? Rescuing. Rescuing one another from the deceitfulness of sin. And doing so because we love one another that much. And we’re okay with making ourselves feel uncomfortable. Yet, we return to sin. Again and again. Because we believe this time it will be different. That is the deceitfulness of sin in its core.

But how do we fight it? How do we overcome it? I wish I could say that this side of eternity, we can overcome sin. We have God’s Word. We have God’s Spirit. We have God’s church. Psalm 119 says, How can a young man keep his way pure? By guarding it according to your word. We must be slaying sin in our lives, killing it. Also, helping one another to kill it. But we don’t stop at merely turning away from it. We’ve got to turn toward Christ. If we don’t exhort one another to look to Christ, man, we’re just weak therapists. It’s only when we see Christ in His power and His glory that our hearts truly change. The presence of God that melts what sin hardens. And we remember how wonderful our Savior is, that He’s with us every day, even until the end of the age.

So, so far, Hebrews has shown us two essential realities of the Christian life for the faithful church. First, we must watch carefully over one another’s souls because the heart hardens so easily. The second one is we must actively encourage one another every day, as long as it’s called today. To fight sin and keep looking to Christ.

Point 3: The Faithful Church Helps One Another Persevere as Those United to Christ

The Hope — Hebrews 3:14–15

But now the author shows us why. He shows us why all of this matters so deeply. Why is this daily encouragement so necessary? Why does perseverance matter so much? Because Christianity… It’s not merely about starting well. It’s about continuing in Christ all the way to the end. And that leads us to point number three. The faithful church helps one another persevere. Notice, as those united to Christ. And that second part is key. Verses 14 to 15.

For we have come to share in Christ. I just want to stop there. Sorry. We have come to share in Christ. If indeed we hold our original confidence firm to the end, as it is said, today, there it is again, if you hear His voice, do not harden your hearts. It’s in the rebellion.

Hebrews loves to repeat. But verse 14 says, is one of the sweetest statements in our text. We have come, help me out, people, pray for me, I’m losing it. We have come, we have come to share in Christ. Christian, think about that. We don’t merely admire Christ, we are united to him. This is all work of God. You didn’t place yourself into Christ. You didn’t make it happen. God did it. And now you’re sharing it. Now rejoice over it. You have died and your life is now hidden with Christ. You don’t live anymore. It’s Christ who lives in and through you.

Can I have that spray over there? There we go. You are the branches. She caught it, didn’t she? You’re good. You’re good. You no longer live. It’s Christ who lives in and through you. You are the branches. He is the vine. Abide in Him and you will bear much fruit. All of your spiritual life comes from Christ. Rest in that. Abide in that. Don’t forget that.

It’s our living union with the living God that changes everything. Without Christ, our church becomes behavior modification. Try harder. Do better. Fix yourself. Christianity is not self-improvement. It’s union with the living Christ. You cannot live the Christian life apart from abiding in him. Spurgeon says, and he captures this beautifully, The grace that is in Him is for us. So much of Christianity is focused on what Christ can give us instead of Christ Himself. We want peace. We want purpose, strength, joy. But all of those things are found in union with Christ.

Christian, Christ is your life. Every grace flows from Him. Every strength comes from Him. Every fruit grows from abiding in Him. Calvin said that all the benefits of salvation become ours only through this important doctrine, the union with Christ. All of the benefits of salvation are ours through this, our union with Christ. Christian, you are not left to live the Christian life in your own strength. The same Christ who saved you is the same Christ who sustains you.

We can describe the Christian life this way. Prayer… Instead of drudgery, is communion with the living God. Obedience, instead of awe, is participation in the kingdom work. Suffering is fellowship with Jesus. Christ is not distant from His church. He walks among His people. He speaks through His Word. He comforts through His people. He strengthens weak saints through ordinary means of grace. And instead of, did I perform well enough in my faith? We simply rest in the finished work of Christ. We keep clinging to Christ. We’re not passive observers. We’re active participants with the living God. Husband and wife. One flesh. What one does affects the other. Only a faint picture of our union with Christ.

And verse 14 gives us another warning. If we hold fast. Now, that may sound like it’s a lot up to you. You better hold on to Christ. Because if you don’t hold on to Him, He’s just going to let you go. No, no, no, no. Perseverance proves our union. It doesn’t earn it. He will never let us go. Here’s another way to say it. We were never truly in Christ if we do not hold fast to the end. There are people who profess Christ for a season and then later they walk away. What did that reveal? Not that Christ failed to keep them, but that perseverance proves union with Christ. It doesn’t earn it. True believers continue with Christ because Christ continues with them.

What is this original confidence that he speaks about? It’s that joyful assurance we first had when we came to Christ. My sins are forgiven. Christ is mine. Heaven is my home. And where God truly changes the heart, the confidence will endure. Nonetheless, we’ve got to keep guarding our hearts. Lord, keep me tender. Keep me receptive to Your Word. Don’t allow my heart to become cold and hardened. I need to live in constant communion with God. You are the joy of my heart. You are my strength and my portion. I need you. I need to feed upon your word and fellowship with you in prayer. I need the church. I need to keep looking to you, Jesus.

And the church is one of God’s means of grace to help us to persevere all the way to the end. The end means one of two things. Either the Lord calls us home or Christ returns in glory. One day, this perseverance will become sight. This is why Scripture continually reminds us, stay sober, stay vigilant, don’t put your guard down, but also be looking out for your brothers and sisters. Stay connected with this body, with this group of believers. Why? Because anything that separates from the body will die. Hand can’t live on its own. Leg can’t survive. And that’s why we keep resting in Christ.

That’s why the author repeats the warning from verse 7 and 8. Today, if you hear His voice, don’t harden your hearts. Embrace God’s salvation graciously offered to you. Don’t let your senses grow dull. Perceive. Listen closely. Jesus said, my sheep will hear my voice and follow me. There’s nothing sweeter than the voice of our Savior, and there’s nothing more precious than when God softens our hearts through His Word. But if we stop listening, we are sure to start sinning. And the longer we resist him, the harder our hearts become.

Let’s not be like the Israelites who rebelled against God. Let’s remember we are the clay. He is the potter. He’s doing a work in our lives. Sometimes we see it. Sometimes we don’t. But that doesn’t mean we stop trusting him. Church, listen, this is our hope. We are not holding on to Christ by the strength of our grip. Christ is holding on to us. And one of the ways He keeps His people is through His people. Through prayers. Through encouragement. Through warnings. Through ordinary faithfulness. He will never let go of his sheep. The shepherd who called us is the shepherd who keeps us. Not for a moment has he stopped watching over his people.

As our confession says, though believers may fall into grievous sins through temptation and neglect of the ordinary means of preservation, Yet they shall be renewed through repentance and be preserved through faith in Jesus Christ all the way to the end. So let’s receive the warnings of Scripture. Let’s hold fast to the promises of Christ. Let’s keep walking together until this faith becomes sight. And on that day, on that day, we will discover that through every warning, every prayer, every act of encouragement, every ordinary means of grace, Christ was faithfully holding his people all the way along.

Conclusion and Application

So as we close, we began by looking at the modern church. Radical, revolutionary, relevant. But Hebrews… Reminds us that the ordinary Christian life is much quieter than that. It’s ordinary faithfulness, ordinary repentance, ordinary encouragement, ordinary perseverance. And through those ordinary means, God does do ordinary things. He preserves His people. And one of the ways that he does that is through the faithful church.

The faithful church watches over one another’s souls.

The faithful church encourages one another, fights in, look to Christ.

And the faithful church helps one another persevere as those united to Christ.

I don’t want you to miss or underestimate the importance of ordinary faithfulness. A word of encouragement A prayer, a loving warning, a simple text message, showing up on the Lord’s day when you don’t feel like it. These are some ordinary means that God uses to preserve His people to the end. So be an encourager. Press into the lives of others around you. And if you’re struggling, discouraged, or weary, do not isolate yourself. You need the church, and the church needs you.

Most importantly, keep looking to Christ because our hope, again, our hope is not ultimately in the strength of our grip on Christ, but in His grip on us. He will never let go of His sheep. Never! Never! So let us receive the warnings of Scripture. Hold fast the promises of Christ. Keep walking together until faith becomes sight. And on that day, we will discover that. Those warnings, those prayers, those encouragements, every ordinary means of grace. The shepherd never lost sight of his sheep. Not for a single moment.

Closing Prayer

Let’s ask the Lord now, let’s ask Him to make these things true in our hearts. Take a moment and I’ll pray.

Oh Lord, we’re so thankful to have just a quiet moment before you in our restless lives, in our anxious souls, looking for the big and the bold and the spectacular and the next best big thing. Oh Lord. Forgive us for all that, making idols out of things you never called us to. Lord, we’re grateful for the ordinary. We know it’s not popular. We don’t care. We want to be faithful to you. We want to serve you with all of our heart, soul, and strength. We know we’ll never be able to do it fully, but that doesn’t stop us from trying. We’re so grateful that one day you will restore us. You will complete the work. No longer will we struggle with this body of death and this sin nature and all the temptations, everything of this world. So just help us, please, Lord, to be faithful every day. To do the little things. And to honor you as we do them. So fill us, oh God, with your spirit. We’re grateful that you’ve sent another helper. We’re grateful that we don’t have to rely on our own strength, but you will accomplish it all for your glory. And we pray this in Jesus’ name.
