1 John 1: 6 - 9

⁶If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:
⁷But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
⁸If we say that we have no sin, we deceive ourselves, and the truth is not in us.
⁹If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.

Job 33: 27 - 28

²⁷He looketh upon men, and if any say, I have sinned, and perverted that which was right, and it profited me not;
²⁸He will deliver his soul from going into the pit, and his life shall see the light.

Psalms 32: 5

⁵I acknowledge my sin unto thee, and mine iniquity have I not hid. I said, I will confess my transgressions unto the LORD; and thou forgavest the iniquity of my sin. Selah.

Proverbs 28: 13

¹³He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.

2 Chronicles 6: 24 - 27

²⁴And if thy people Israel be put to the worse before the enemy, because they have sinned against thee; and shall return and confess thy name, and pray and make supplication before thee in this house;
²⁵Then hear thou from the heavens, and forgive the sin of thy people Israel, and bring them again unto the land which thou gavest to them and to their fathers.
²⁶When the heaven is shut up, and there is no rain, because they have sinned against thee; yet if they pray toward this place, and confess thy name, and turn from their sin, when thou dost afflict them;
²⁷Then hear thou from heaven, and forgive the sin of thy servants, and of thy people Israel, when thou hast taught them the good way, wherein they should walk; and send rain upon thy land, which thou hast given unto thy people for an inheritance.

Acts 3: 19 - 20

²⁰And he shall send Jesus Christ, which before was preached unto you:

Luke 15: 21 - 24

²¹And the son said unto him, Father, I have sinned against heaven, and in thy sight, and am no more worthy to be called thy son.
²²But the father said to his servants, Bring forth the best robe, and put it on him; and put a ring on his hand, and shoes on his feet:
²³And bring hither the fatted calf, and kill it; and let us eat, and be merry:
²⁴For this my son was dead, and is alive again; he was lost, and is found. And they began to be merry.
