The Bible contains many books, authors, and events, but it tells one unfolding story of God’s grace in Jesus Christ.
After Adam sinned, God promised that the offspring of the woman would crush the serpent’s head (Gen. 3:15). That promise was revealed more fully through God’s covenants with Noah, Abraham, Israel, and David. These covenants weren’t separate plans of salvation. Together, they pointed forward to Christ and the new covenant He would establish through His blood.
At the Last Supper, Jesus said, “This cup that is poured out for you is the new covenant in my blood” (Luke 22:20).
Covenant theology helps us understand that Scripture isn’t a collection of disconnected stories or moral lessons. From Genesis to Revelation, God is carrying out His one gracious plan to redeem a people through His Son.
God promised Abraham that all nations would be blessed through his offspring. Paul tells us that this promised offspring is Christ (Galatians 3:16). God promised David a Son whose kingdom would endure forever. Jesus is that King. The sacrifices, priests, and ceremonies given to Israel pointed beyond themselves to the Savior who would offer Himself once for all.
Every promise of God finds its “Yes” in Christ (2 Cor. 1:20).
This changes how we read the Bible. Noah’s ark, Abraham’s family, Israel’s deliverance, David’s throne, and the temple sacrifices all belong to the unfolding story that leads us to Jesus. Scripture is ultimately not a story about heroic people reaching God, but about our covenant-keeping God coming to save covenant-breaking sinners.
It also strengthens our assurance. Our salvation doesn’t rest upon our ability to keep our promises to God. It rests upon Christ, who fulfilled every promise and secured the new covenant with His own blood. In Him, our sins are forgiven, God’s law is written upon our hearts, and we belong to Him forever (Heb. 8:10-12).
As you read Scripture this week, ask: How does this passage fit within God’s unfolding plan of redemption, and how does it lead me to trust Christ more fully?
The whole Bible tells one story, and at its center stands one sufficient Savior.
