'Repentance' in the Bible

I have not come to call the righteous to repentance, but sinners."

I tell you that in the same way there will be rejoicing in Heaven over one repentant sinner--more rejoicing than over ninety-nine blameless persons who have no need of repentance.

and that proclamation would be made, in His name, of repentance and forgiveness of sins to all the nations, beginning in Jerusalem.
