“If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness” (1 John 1:9).“I write unto you, little children, because your sins are forgiven you for His name’s sake” (1 John 2:12).“In Whom we have redemption through His blood, the forgiveness of sins” (Ephesians 1:7).These verses refer to all sins, past, present, and future.All of these sins are forgiven when we first come to Christ; this is judicial, eternal forgiveness provided by God as Judge.If we sin after we come to Christ and confess them as in 1 John 1:9, we receive paternal and restorative forgiveness provided by God as Father.This forgiveness restores us to fellowship with God and to the joy of His salvation (Psalm 51:12).Confession is a result of repentance and is taking sides with God against ourselves and admitting that we have done wrong.This admission restores communion between God and ourselves.
