Should Christians Confess Their Sins — Meaning Explained

First John 1:9 is the cornerstone: 'If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.' Confession (homologeo) means 'to say the same thing' — to agree with God about our sin. David's unconfessed sin brought misery: 'When I kept silence, my bones waxed old through my roaring all the day long' (Psalm 32:3). When he confessed, God forgave: 'I said, I will confess my transgressions unto the LORD; and thou forgavest the iniquity of my sin' (Psalm 32:5). Psalm 51 is David's powerful confession after his sin with Bathsheba. James adds a corporate dimension: 'Confess your faults one to another, and pray one for another, that ye may be healed' (James 5:16). This is not auricular confession to a priest but mutual accountability among believers. Proverbs 28:13 summarizes: 'He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.'
