Eddie,
What you say makes no sense to me. Who says that everything has a cause? Natural laws say that every effect has a cause! The Almighty God was the First Cause, Jesus was the Second Cause. What caused God Almighty? Nothing, because God always existed. Causes can begin in the mind, because we can think and imagine.
Your posits are called Paromologia, which just depends on a play on words, like saying the Almighty God cannot create a rock to heavy for Him to lift.
What is the difference between freewill, and just will of any kind?
I believe that Ecclesiastes 11:9 shows that we all have freewill. Notice, the Scripture says that we can choose to walk in the ways of our heart and in the sight of your eyes, BUT know that you will be brought to Judgement for all the things you do. God does not want you to do the bad things of your youth, but you have freewill to do things that God does not approve of. People have until Jesus comes back to earth to make up their mind to obey God.
Genesis 6:5,6.
I too believe in a God who is a Supreme Being who is uncaused and who caused all things
And how this thread played out actually has convinced me I do have free-will, which I (obviously) somewhat doubted
