1 John 1:9
If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness — confession (homologeō) is both acknowledgment and agreement: agreeing with God's judgment about sin. Faithful (pistos) and just (dikaios) describe God's covenant reliability and moral consistency. The forensic forgiveness and moral cleansing (katharizō) unite justification and sanctification.
