Nevertheless, I don't doubt there exist individuals who would dare claim sinlessness. But we agree that you and I wouldn't hold such an exalted view of our own righteousness. Think about it for a few moments. I wouldn't say I have never sinned, but sometimes I find it so difficult to admit my sins. My friend, when God says something is wrong, doing it is sin.
All sin requires repentance and forgiveness.
An example should help clarify my point. Suppose you wrong someone. Maybe you gossiped about him or spoke unkindly to her or struck a sibling in anger or went somewhere against your parents' wishes. Don't be so haughty, proud and arrogant that you cannot apologize. Then they wonder why joy, peace, satisfaction and victory elude them.
