The captivity of Judah brought an end to God’s original plan of salvation for his people, known as the Old Covenant. The Old Covenant was based on God’s deliverance of his people from slavery in Egypt. When the Israelites crossed the Red Sea and entered the wilderness, they became an independent people group that was later referred to as the nation of Israel. Everything that happened between God and his people was done collectively as if all the people were a single entity. When the Old Covenant was brought to a conclusion, God began to look at every person on an individual basis to determine their life’s course.

The captivity of Judah was the result of a national failure to obey God. Even though every person was guilty of sinning against God, it was their collective guilt that brought condemnation on God’s people. Describing the new approach God would take, Jeremiah declared, “In those days they shall say no more, the fathers have eaten a sour grape, and the children’s teeth are set on edge. But every one shall die for his own iniquity” (Jeremiah 31:29-30). God make his new covenant “with the house of Israel, and with the house of Judah” (Jeremiah 31:31). The reunification of Jacob’s family and rebuilding of the nation of Israel was an important aspect of God’s revised plan that showed he did not intend to start over or abandon his chosen people in his attempt to save the world.

A critical difference between the old and new covenants was the type of relationship God intended to have with his people. Initially, God acted as a husband to his people (Jeremiah 31:32), and desired an exclusive relationship with them based on a binding legal agreement. After Israel betrayed him and Judah sought military assistance from foreign nations, God determined another way to deliver his people from their sinful behavior. Rather than expecting them to make sacrifices to him, God would enable his people to be forgiven of their sins once and for all. Based on his sovereign right to show favor to whomever he chose, God designated all who accepted his free gift of salvation to be completely absolved of their sins (Jeremiah 31:34).

A description of the new covenant was given to Jeremiah in order to clarify God’s intent in restoring the nation of Israel. He said, “But this shall be the covenant that I will make with the house of Israel; after those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts” (Jeremiah 31:33). God’s ability to transform the human heart was the hallmark of his new covenant. A desire to do the will of God would be evidence that a person had been converted. Not only did God intend to bring his people back to their homeland, but he also intended to live among them (Jeremiah 31:34).
