Biblical Topics A to Z
New Covenant
What the new covenant promised in Jeremiah 31 means, how Jesus establishes it at the Last Supper, and what Hebrews says about its superiority to the old covenant.
Overview
The new covenant, promised by Jeremiah and instituted by Jesus at the Last Supper, fulfills and surpasses the old covenant given at Sinai, writing God's law on the heart rather than on stone and securing complete forgiveness through Christ's own blood.
Learning Objectives
- •Explain what Jeremiah 31 promised about a coming new covenant.
- •Identify how Jesus explicitly linked his death to the new covenant at the Last Supper.
- •Describe why Hebrews calls the new covenant better than the old.
I will put my law in their inward parts, and write it in their hearts... for I will forgive their iniquity, and I will remember their sin no more.
Jeremiah 31:33-34
Read It in Context
This study quotes Jeremiah 31:33-34, but no verse stands alone. Open a Bible and read the whole surrounding chapter to see the full argument the passage sits within, then look up the other references cited throughout this study — Luke 22:20 and beyond — in their own context. Scripture is the final authority here, not this summary.
Historical & Literary Context
Jeremiah prophesied to a Judah about to go into Babylonian exile because of persistent covenant unfaithfulness under the Sinai covenant. Rather than ending the covenant relationship, God promised through Jeremiah a coming, better covenant, one Jesus explicitly identified with his own blood at the Last Supper (Luke 22:20), and which the author of Hebrews explains at length as superior to the old.
An Internal, Not Merely External, Law
Jeremiah 31:33 promises God's law written on the heart, not only on tablets of stone. This anticipates a covenant that transforms desire from within rather than only regulating behavior from without.
Complete and Final Forgiveness
Jeremiah 31:34 promises that God will remember sin no more, a decisive contrast with the old covenant's repeated yearly sacrifices, which Hebrews 10:3-4 says could never actually take away sin, only cover it temporarily.
A Better Covenant on Better Promises
Hebrews 8:6-13 quotes Jeremiah 31 directly, declaring the new covenant better, established on better promises, and describing the old covenant as now obsolete, having been fulfilled in Christ.
Christ-Centered Focus
At the Last Supper, Jesus took the cup and said, 'This cup is the new testament in my blood, which is shed for you' (Luke 22:20), directly fulfilling Jeremiah's promise through his own atoning death, making the new covenant available to all who trust him.
Practical Application
This week, when you take communion, deliberately remember that the cup represents not merely a ritual but the fulfillment of Jeremiah's ancient promise: a covenant of complete forgiveness and a transformed heart, secured by Christ's blood.
Prayer
Father, thank You for the new covenant sealed in the blood of Jesus Christ, in which You have written Your law on my heart and promised to remember my sins no more. Thank You that this covenant rests on better promises than anything I could keep on my own. In Jesus' name, Amen.
Scripture Memory
"Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you."
Luke 22:20
