What does 1 John 1:9 mean?

“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 → BSB · Public Domain (CC0)
Quick answer

“If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness” promises sure forgiveness to those who honestly admit their sin to God. Forgiveness rests on God’s faithfulness, not our performance.

What it means

To “confess” is to agree with God about our sin rather than hide or excuse it. The verse invites honesty, not despair.

God’s response is described as “faithful and just” — he forgives because he keeps his promise and because Christ has already paid for sin. Cleansing is complete: “all unrighteousness.”

Common questions
Does this mean I must confess perfectly to be forgiven?

No. The emphasis is on honest acknowledgment of sin, met by God’s faithful forgiveness through Christ — not on flawless wording or remembering every fault.
