Jeremiah 18

So I went down to the potter’s house, and I saw him working at the wheel.  But the pot he was shaping from the clay was marred in his hands; so the potter formed it into another pot, shaping it as seemed best to him. vv.3-4

Read chapter 18
The potter and the clay.  Have you ever seen a potter at the wheel forming something out of clay.  It's impressive!  The wheel is constantly twirling going at different speeds while the potter's hands shape and mould the clay.  Clay is just mud and useless unless made into something of value.  Potters were very common in the days of Jeremiah, but the Lord wanted Jeremiah to go and get a fresh look as He compares Himself to a potter with the clay being the house of Israel.  God was showing him that He had Israel in His hands, and even though they were marred because of sin, God would reshape them.  God would not just mend them but make new as a potter would make the clay into another vessel if it became ruined. Often it's the hard things in life that have molded who we are today.  When sin surfaces itself in our lives, if we remain soft and moldable, God is able to make us into something new for good purpose bringing Him glory.
As Isaiah 64:8 says, "Yet You Lord, are our Father.  We are the clay, you are the potter, we are the work of your hands."
How is the Lord shaping you today?  Are you allowing the Potter to mold you into making you for a purpose?
