FREE WILL: As Christians, what is wrong with our definition ?

If God is as a Potter, and we are as the clay.....WHO...WHO is in control ? Who is sovereign? who are the "subjects" in His Kingdom? ..." it is God who works in you to will and to do according to his good pleasure..." WHO directs the steps of man? so, as we are the "dust" of the earth, and mixed with his holy waters, hence, the clay, which is "formed" into a vessel to serve his purposes and his pleasure,....NOW, tell me about YOUR free will ....remember,....I'm not particularly interested in the fact that you " FEEL + THINK " that you have "free will". Remember,..." lean not on your own understanding ! "
