What does the Bible say about being made sinful?

In Luke 5, the calling of Peter to follow Jesus is accompanied by the revelation of Peter’s own sinfulness as he declares, 'Depart from me, for I am a sinful man, O Lord.' This illustrates the work of grace in a person's heart, showing them their true condition before a holy God. The essential truth is that without this recognition of sin, we cannot fully understand our need for Christ and His redemptive grace. The miracle here is Peter’s heart being changed, recognizing that he has nothing in himself that mirrors the perfection of Christ.
