A genuinely saved man will not just “quit” wrong to be saved, he will quit wrong because he’s saved. He’s a new creation made by Christ. He’s saved by Grace. He’s justified by Grace. He experiences righteousness by faith. Every sin is forgiven and the heart is clean and holy in the eyes of God. There’s no more “rejection” of Christ, but acceptance and trust with an everyday consciousness to Christ’s Divine presence and authority. There’s a transformation made where the clean heart provides a means for the believer in Christ to live without sin.
I know this state of being is not experienced by everyone, but the fact of the matter is, “Everybody is not genuinely saved”.
