Calvinists say regeration must come before "born again" can occur in man. Regeneration is the Holy Spirit washing away the man's sin nature thus renewing man's spirit so that man can have faith in God. And those to whom this is done did nothing, not even hear the word of God, until the regeneration was complete, and that they were predicted from before the foundation of the world to receive this regeneration. Non Calvinists say, "Born again" is the man hearing the word of God and believing, which is a change of personal spiritual persuasion, thus enabling him to be washed clean of his sin nature through acknowledgement of ones sin, confession of sin that results in forgiveness and cleansing from all unrighteousness. The one hearing and believing is not necessarily predicted to do so from the foundation of the world.
