Human freewill pretty much boils down to self will. It is not a super power in anyway. We can chose to follow God or not, but we have no choice in the consequences or judgment of God that follows that decision. He already said Believe upon Jesus or Perish. There is no way to change that outcome.The consequences negate freewill ... he was able to rebel against God's will and that is what he did.
If he had freewill Adam would have chosen to sin but not die ... that was the deception the devil perpetrated on him.
Human freewill is that deception
Self will is found in the soul realm of man. There are three components of the soul of man; self will, intellect (thoughts or mind), and emotions. Self will says I want, I don't want, I will or I won't. It has no other power but choice. In order to be saved we have to put our trust in Jesus and submit that self will to the Spirit. If we don't then we will reap the consequences.
Faith comes by hearing the Word of God, the Holy Spirit convicts of sin, lights up the way, and leads (draws) us to JESUS. It is our choice whether to submit our self will to the Spirit and trust in Jesus or not. In order to be born again we have to repent, turn and submit our self will to the Lord. After doing that, the spirit within us is regenerated (born again). The spirit comes back to life, all sin is forgiven. There is no more separation between us and God. We are then able to have direct communion with God and walk with the HIM in the Spirit .
