1 John 1:9: Confession and God's Faithfulness
First John 1:9 makes confession a promise built on God's own character: he is faithful and righteous to forgive. It is the way we receive what Christ has already secured, not a transaction that earns mercy.
1 John 2:1–2: Sin After Salvation
John writes so that his readers may not sin, then immediately points the one who does sin to an advocate with the Father. The passage holds a clear aim of obedience together with real provision for the guilty.
