The new covenant is God’s promise, first announced through the prophet Jeremiah, to forgive his people completely and write his law on their hearts. Hebrews explains that Jesus fulfilled that promise. The old covenant relied on repeated animal sacrifices that could never truly remove sin, but Jesus offered himself once for all. Through him, believers have full forgiveness and direct access to God, even as we wait for his kingdom to come in full.
A Promise Worth Waiting For
Anyone who has taken a long road trip with kids knows the question: “Are we there yet?” For centuries, God’s people were asking something similar. God had made great promises, but the timeline for their fulfillment was unclear. Then, through Jeremiah, God announced something new.
Jeremiah 31:31-33 “The days are coming,” declares the Lord, “when I will make a new covenant with the people of Israel and with the people of Judah. It will not be like the covenant I made with their ancestors when I took them by the hand to lead them out of Egypt, because they broke my covenant, though I was a husband to them,” declares the Lord. “This is the covenant I will make with the people of Israel after that time,” declares the Lord. “I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people.
A covenant is different from a contract. A contract says, “You do your part, and I’ll do mine.” A covenant is relational, more like a marriage vow: “I will be faithful to you.” God made several covenants in the Old Testament, with Noah, Abraham, Moses, and David, and each one pointed forward to something greater.
The Old Covenant Couldn’t Remove Sin
At Mount Sinai, God gave Israel the Mosaic covenant. Its sign was the Sabbath, a weekly reminder that their lives depended on God, not on their own labor. But this covenant was also conditional. Obedience brought blessing, and disobedience brought discipline, and Israel broke the covenant again and again. You can read more in What Was the Mosaic Covenant All About?
God graciously provided the sacrificial system so people could deal with their sin. Hebrews 9:22 says that without the shedding of blood there is no forgiveness. The sacrifices weren’t about a bloodthirsty God; they showed how costly sin really is.
Hebrews 10:3-4 But those sacrifices are an annual reminder of sins. It is impossible for the blood of bulls and goats to take away sins.
The sacrifices were reminders, not solutions. Year after year, the problem of sin was covered but never fully removed.
Jesus Fulfilled the New Covenant
That’s where Jesus changes everything. He is both the High Priest and the sacrifice. Old Testament priests stood day after day because their work was never finished. Jesus offered himself once, and then he sat down.
Hebrews 10:11-14 Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins. But when this priest had offered for all time one sacrifice for sins, he sat down at the right hand of God, and since that time he waits for his enemies to be made his footstool. For by one sacrifice he has made perfect forever those who are being made holy.
Every covenant in the Bible finds its fulfillment in him. He took the judgment the Noahic covenant pointed to, he brings the blessing of Abraham to people from every nation, he kept the law of Moses perfectly and became the final sacrifice, and he is the eternal King promised to David.
Living Between Already and Not Yet
Hebrews 10:13 adds an important detail: Jesus now “waits for his enemies to be made his footstool.” His kingdom has already begun, but it hasn’t fully arrived. Sin still affects our lives, and the world is still broken. In one sense, we’re still in the back seat asking, “Are we there yet?”
Hebrews 10:19-22 Therefore, brothers and sisters, since we have confidence to enter the Most Holy Place by the blood of Jesus, by a new and living way opened for us through the curtain, that is, his body, and since we have a great priest over the house of God, let us draw near to God with a sincere heart and with the full assurance that faith brings, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water.
The difference is that the waiting is no longer uncertain. Forgiveness is already ours, the way into God’s presence is already open, and we know exactly where the road ends. Because of Jesus, we can wait with confidence. If you’d like to learn more about putting your faith in Jesus, check out How can I become a Christian?
The Takeaway
The new covenant is God’s promise to forgive sin completely and bring his people close, and Jesus fulfilled it through his once-for-all sacrifice. We still wait for his kingdom to come in full, but we wait as people who already have full access to God.
