He molds us and makes us after his will and the end product is a vessel which demonstrates His artistry. We, Christians are God's craft-exhibits. During this time of year, there are a lot of Craft-fairs and harvest celebrations. If you ever attend craft fairs, some of the big ones can be pretty impressive. Hundreds of weaves, crafts, carved woods, etc. are on display.
Every object represents many hours of work, great creativity, and design.
If you've ever made any crafts, even small one, you can see how much work is involved. We are a display of God's creativity and artistry. As in verse 7, He has an eternal fair. The Master-Craftsman refines us, and molds us. He puts us on the Potter's wheel and it is he who fires the kiln.
