If We Say We Have No Sin
8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and righteous to forgive us the sins and to cleanse us from all unrighteousness. 10 If we say that we haven’t sinned, we make him a liar, and his word is not in us.
Two claims to sinlessness are quoted and answered, and between them stands the letter's promise about confession.
The quoted claims in verses 8 and 10 are not identical, and the difference matters. The first denies having sin — a condition. The second denies having sinned — a record. The letter refuses both, which closes the escape route of admitting a nature while denying any actual act.
The verdicts escalate. Claiming no sin deceives ourselves and leaves the truth out of us. Claiming never to have sinned makes God a liar, because it contradicts what he has said. Self-deception in the first case, contradiction of God in the second.
Verse 9 sits between them and is the most quoted sentence in the letter. Its terms are precise. Confession is agreement — saying the same thing about the act that God says. And the two adjectives describing God's response are the striking part: faithful and righteous to forgive. Not merciful, not kind, though he is both. Faithful means he keeps something promised; righteous means the forgiveness is just rather than indulgent. The letter has already named what makes it so 1 John 1:7, and will name it again 1 John 2:2.
The outcome is stated twice over, forgiving the sins and cleansing from all unrighteousness — the record dealt with, and then the stain.
