This message works through 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” – unpacking why a holy God can forgive sinners without compromising His justice. He first defines sin and depravity: it is not just a list of bad deeds but a corruption that colors every part of a person – mind, will, emotions and actions – so that people sin because they are sinners by nature, not sinners merely because they sin.
Part 2 continues into what it means that God is “faithful and just” both to forgive and to justify, showing that forgiveness and justification rest on God’s own character and Christ’s finished work, not on the sinner’s effort. The series closes by pointing believers back to honest confession as the ordinary way a Christian keeps walking with a forgiving God.
