31 "The day is coming," says the Lord, "when I will make a new covenant with the people of Israel and Judah. 32 This covenant will not be like the one I made with their ancestors when I took them by the hand and brought them out of the land of Egypt. They broke that covenant, though I loved them as a husband loves his wife," says the Lord . 33 "But this is the new covenant I will make with the people of Israel after those days," says the Lord . "I will put my instructions deep within them, and I will write them on their hearts. I will be their God, and they will be my people. 34 And they will not need to teach their neighbors, nor will they need to teach their relatives, saying, 'You should know the Lord .' For everyone, from the least to the greatest, will know me already," says the Lord . "And I will forgive their wickedness, and I will never again remember their sins."

35 It is the Lord who provides the sun to light the day and the moon and stars to light the night, and who stirs the sea into roaring waves. His name is the Lord of Heaven's Armies, and this is what he says: 36 "I am as likely to reject my people Israel as I am to abolish the laws of nature!"

Commentary on Jeremiah 31:27-34

(Read Jeremiah 31:27-34)

The people of God shall become numerous and prosperous. In Hebrews 8:8,9, this place is quoted as the sum of the covenant of grace made with believers in Jesus Christ. Not, I will give them a new law; for Christ came not to destroy the law, but to fulfil it; but the law shall be written in their hearts by the finger of the Spirit, as formerly written in the tables of stone. The Lord will, by his grace, make his people willing people in the day of his power. All shall know the Lord; all shall be welcome to the knowledge of God, and shall have the means of that knowledge. There shall be an outpouring of the Holy Spirit, at the time the gospel is published. No man shall finally perish, but for his own sins; none, who is willing to accept of Christ's salvation.

Commentary on Jeremiah 31:35-40

(Read Jeremiah 31:35-40)

As surely as the heavenly bodies will continue their settled course, according to the will of their Creator, to the end of time, and as the raging sea obeys him, so surely will the Jews be continued a separate people. Words can scarcely set forth more strongly the restoration of Israel. The rebuilding of Jerusalem, and its enlargement and establishment, shall be an earnest of the great things God will do for the gospel church. The personal happiness of every true believer, as well as the future restoration of Israel, is secured by promise, covenant, and oath. This Divine love passes knowledge; and to those who take hold upon it, every present mercy is an earnest of salvation.
