You are not the potter you are the clay. Clay does not decide what it wants to be, does not have control over what form it will take...that's the potters job. Clay is completely dependent on the potter to be shaped....clay does not shape and mold itself. Clay cannot stop the wheel from spinning and get off...not until the potter is done.
It is the potter who has the plans for the clay, he is the one turning the wheel, shaping, forming, molding and reworking the clay until he has made it into a vessel that will be used for his specific purpose...his purpose not yours. Remember, clay does not decide what form it is going to take...and remember this, without the potter you would be just a lump of clay.
Yet, O Lord, you are our Father. we are the clay, you are the potter we are the work of your hand
