Jeremiah 31:33 I will be their God and they shall be my people.

The prophet is talking about a whole new arrangement, a whole new covenant between God and the people. Instead of the old covenant, where leaders and teachers had a lot of control over the people, Jeremiah envisions a way of life where all the people know God and love him, from the greatest to the least. His name is written on their heart, and they are his. We see here a very early glimpse of the life and ministry of Jesus.
