Jeremiah 18:1-4
The word which came to Jeremiah from the Lord, saying: “Arise and go down to the potter’s house, and there I will cause you to hear My words.” Then I went down to the potter’s house, and there he was, making something at the wheel. And the vessel that he made of clay was marred in the hand of the potter; so he made it again into another vessel, as it seemed good to the potter to make.

I’ve only watched videos of a potter with clay on his wheel. I have not witnessed it in person but understand the concept.
The potter is a craftsman that takes his work very personal. He gets his hands dirty with it.
With his hands, he forms on the potter’s wheel what he visions in his mind. He has an image of what the clay should become and works to create it.
He feels any impurities in the clay like a lump or a rock. He feels whether it’s too wet or too dry.
He can make anything. Perhaps he forms a flower vase one time and a plate the next. Both are useful items but one is used more often.
Once the potter finishes he cures his creation with fire in a kiln.
Only after this is the clay ready to decorate for use.

God has formed us in His image. All of us are His creation.
I want to be a useful vessel for Him, not something that sits on a shelf but something He uses every day.
I believe the Holy Spirit is the fire of the kiln that makes us useful for the Lord.
Without the Holy Spirit, we can do nothing for the Lord.
