1 John 2:1-4; 1 John 1:8

1 John 2:1-4

1 My little children, I am writing these things to you so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous;

2 and He Himself is the propitiation for our sins; and not for ours only, but also for those of the whole world.

3 By this we know that we have come to know Him, if we keep His commandments.

4 The one who says, "I have come to know Him," and does not keep His commandments, is a liar, and the truth is not in him;

1 John 1:8

8 If we say that we have no sin, we are deceiving ourselves and the truth is not in us.
