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
We have a problem: God is righteous, and we are unrighteous. Because of sin our very nature is the opposite of His. We act and think and respond in ways contrary to His ways. We need forgiveness for our wrongs, and we need who we are to be changed.
God wants us to be honest with Him. Honest about our actions and honest about ourselves. It is often harder to admit who we are than to confess our deeds. But to God, this is the very point of his faithfulness.
He forgives us. All of the wrong things we have done have been forgiven because of the death and resurrection of Jesus. But more than that He changes who we are and He takes away our unrighteousness, the ways in which we are opposite to Him. God deals with our sin, and He deals with us as sinners. He does so in a remarkable, loving way — by forgiving us and by cleansing us. It is remarkable because God does this through His love for us. He wants to be with us, and wants us to be all the things He created us to be.
When we have done wrong, made mistakes, or willfully sinned, we have an immediate way back to our Father. We admit to God what we have done, and we admit who we are. By simply confessing we have a way back to His love and forgiveness.
All our sin and guilt have already been taken care of by Jesus. How wonderful to be able to admit our failures, when we know we have already been forgiven! Although we struggle and fail, we need only come back to our Father each time. He is faithful.
