Confess yourself to heaven; Repent what’s past; avoid what is to come. – William Shakespeare Hamlet, Act 3, Scene 4. Hamlet tells his mother to admit her sin in marrying her husband’s brother and avoid damnation.
They that are whole need not a physician; but they that are sick. I came not to call the righteous, but sinners to repentance. – The Bible Jesus Christ, Luke 5:31-32.
