Godly sorrow worketh repentance not to be repented of.
~ 2 Cor 7:10
Peter remembered the word of Jesus, which said unto him, Before the cock crow, thou shalt deny me thrice. And he went out, and wept bitterly. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. The blood of Jesus Christ his Son cleanseth us from all sin.
Mine iniquities have taken hold upon me, so that I am not able to look up; they are more than the hairs of my head: therefore my heart faileth me. Be pleased, O Lord, to deliver me: O Lord, make haste to help me.
Turn thou to thy God: keep mercy and judgment, and wait on thy God continually.
The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise. He healeth the broken in heart, and bindeth up their wounds. He hath shewed thee, O man, what is good: and what doth the Lord require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?
