Jeremiah 31:33 promises that God will make a new covenant in which his law is no longer carved on stone or kept only in written scrolls, but placed within his people and written on their hearts. The result is a relationship where God says he will be their God and they will be his people. The words come from the prophet Jeremiah, who speaks on God’s behalf to the people of Israel during a time of national crisis and exile.
“But this is the covenant that I will make with the house of Israel after those days,” says the LORD: I will put my law in their inward parts, and I will write it in their heart. I will be their God, and they shall be my people.

What Jeremiah 31:33 Means
The phrase “I will put my law in their inward parts” describes a change from outside to inside. Israel had received the law at Sinai as external instruction, and they often knew it without living it. God says the new covenant will reach the deepest place of a person, the place where desires, decisions and loyalties are formed. The law stops being a list you check and becomes a pattern you naturally want to follow.
“I will write it in their heart” uses the same idea in another image. Writing on the heart means the law becomes part of who a person is, not merely something they consult. The verse then ends with the heart of the covenant: “I will be their God, and they shall be my people.” Everything else in the verse flows from that closeness.
The verse does not promise that people will never struggle, never sin, or never need instruction. The surrounding passage makes clear that God will forgive sin, which implies that failure remains a real part of life. What the verse promises is a change of inner orientation that God himself accomplishes.
The Context of Jeremiah 31:33
The book of Jeremiah was written during the final decades before Judah fell to Babylon in 586 BC. Jeremiah was a priest from Anathoth who spoke many hard words of warning to the kings and people of Judah. Chapters 30 to 33 are often called the “Book of Consolation,” because after so much judgment, God speaks words of restoration and future hope. Tradition attributes the book to Jeremiah, with his scribe Baruch involved in recording his words.
Just before verse 33, God says that people will no longer be punished for the sins of their parents, and that the new covenant is not like the one made when he led Israel out of Egypt, a covenant they broke. Verse 34 then continues the thought: people will no longer need to tell one another to know the LORD, because all will know him, and God will forgive their iniquity. Read in this setting, verse 33 is the center of a promise that the old covenant’s failure will be answered by a deeper, inward work of God.

A Short Prayer From Jeremiah 31:33
Lord, you know how often I know what is right but do not want to do it. Write your law on my heart so that your ways become my own desires, not just rules I try to keep. Forgive me where I have failed, and remember my sin no more, as you promised. Make me one who knows you personally and walks with you each day. Amen.
