Which is really my point. God ain’t forgiving anyone their sins when they deny them.
Everyone harbors a vast host of sins. If God waited for a full confession of all sin to happen before accepting one who knows he is a sinner for salvation... nobody would get accepted. Just the need as a sinner requires acknowledgment, and the faith that the merciful Lord will help them get their life right.
Get off your hobby horse of condemnation and start pointing to the Lord.
