If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say that we have not sinned, we make Him a liar, and His word is not in us. (1 John 1:9-10 NKJV)
Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, fervent prayer of a righteous man avails much. (James 5:16 NKJV)
For day and night Your hand was heavy upon me; my vitality was turned into the drought of summer. Selah
I acknowledged my sin to You, and my iniquity I have not hidden. I said, "I will confess my transgressions to the LORD," And You forgave the iniquity of my sin. Selah
For this cause everyone who is godly shall pray to You in a time when You may be found... (Psalm 32:4-6 NKJV)
He who conceals his sins does not prosper, but whoever confesses and renounces them finds mercy. (Proverbs 28:13 NKJV)
Have mercy on me, O God, because of your unfailing love. Because of your great compassion, blot out the stain of my sins. Wash me clean from my guilt. Purify me from my sin. For I recognize my rebellion; it haunts me day and night. Against you, and you alone, have I sinned; I have done what is evil in your sight. You will be proved right in what you say, and your judgment against me is just. (Psalm 51:1-4; 5-19 NLT)
