In this passage, Jeremiah is instructed to visit the potter's house as an analogy for how God relates to His creation. The main message is that God has the freedom to respond to His creation in relationship. Because He is sovereign, He is free to change His mind in response to people's attitudes toward Him. The message to Israel is that He is planning discipline for them. The message to us is that God treats us more than fairly, using His sovereignty to respond to us in relationship.
