What precisely is the difference between 'will' and 'free' will?
''It can be an act of God's will that he opened ones heart to religion, born again or revert.''
That's not even an example of what 'will' is how 'will' works. What you say here is God interfering with the normal of human decision making. Which has nothing to do with the will of the person who has had his or her 'heart opened'
''Free will is coming to ones own choices, you are free to believe or not it's up to you or fast or not''
So you are quite able to choose to not believe what you are now convinced is true? You believe in the existence of the God of the bible, but you can, if you so wish, dismiss your belief in God?
