“If we say that we have no sin, we are deceiving ourselves and the truth is not in us. If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness” (1 John 1: 8-9).
To confess one’s sin is to say the same thing as God regarding a matter. Most of the time we don’t have a very accurate assessment our shortcomings. What God’s word would define as sin, we dismiss as an addiction, a disease, a predisposition. Until we confess and agree with God on those things that are destructive and impede the accomplishment of His purposes in our life, we can never move forward. It’s not about wallowing in guilt but wanting more.
