Can we cure ourselves of sin?

The Scripture makes it clear that humans cannot cure themselves of sin. Job 14:4 asks, 'Who can bring a clean thing out of an unclean?' demonstrating that our sinful nature prevents us from achieving righteousness on our own. The analogy of a rag soaked in motor oil illustrates the futility of trying to clean ourselves from sin; just as one cannot clean an oil-soaked rag, we cannot purify our hearts. Instead, God requires a perfect obedience to His law, which we cannot fulfill because of our corrupted nature. Therefore, we rely solely on Christ, the great Physician, for our healing and redemption.
