Yes, it does. 1 John 1:9 says if we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. So confession is dealing with forgiveness according to 1 John 1:9. In Luke 18:9-14, Jesus essentially said that the Tax Collector was justified and the Pharisee was not. In the Parable of the Prodigal Son, we see the Prodigal Son was restored by his coming back home and in seeking forgiveness with his father. His father said he was "dead" and he is now "alive again." He was dead spiritually and he became alive again spiritually via by seeking forgiveness with his father (Luke 15:11-32). In our case, this would be our Everlasting Father (Jesus). Proverbs 28:13 gives us two requirements to have mercy. Confessing and forsaking sin. Peter tells Simon the sorcerer to pray to God so as to seek forgiveness with Him in the hope of forgiveness over his trying to pay for the Spirit and the gifts thereof. His heart was not right with God by what he did, and he needed to seek forgiveness with God.
