NSB(i)
1 My little children, I write you these things that you may not sin. If any man sin, we have an Advocate (intercessor) (comforter) (helper) with the Father, Jesus Christ the righteous!
2 He is the propitiation (Greek: hilasmos: atonement, compensation) for our sins. Not for ours only, but also for the whole world.
3 We know that we know him, when we obey his commandments.
