This is a huge question and one that would take more than one blog article. However, have you ever done a study on the Greek word epistrepho as it relates to conversion? Consider this definition and then look up the word and verses which occurs 48 times in the New Testament.
Epistrepho means to turn back to transform, to convert as a one time event that continues in action where God turns a man to Himself and the man therefore turns back to God. This man's entire nature and essence is changed, his soul is changed progressively back into the image of God that was lost in the garden of Eden.
Conversion therefore includes two things:
1. Regeneration which is the 100% act of God in which there is a supernatural transformation whereby the principle of spiritual life is imparted by bringing a man under the state and dominion of righteousness.
2. Repentance and faith are the two things that issue out from this regeneration. Though it can be said that regeneration is an act of God alone, conversion is an act of God and man. A man cooperates freely because he has been made willing and able by divine grace.
