Take with you words and return to the LORD; say to him, Take away all iniquity; accept what is good, and we will pay with bulls the vows of our lips.
Hosea 14:2

There's no sacrifice for deliberate rebellion against God except confession and repentance, and false repentance will never fool God who sees every dark corner of our hearts. Only sincere repentance counts. It's better not to repent at all than to repent falsely. Don't play games with God.
