If we say that we have fellowship with him and walk in the darkness, we lie and do not practice the truth.

If we say that we do not have sin, we deceive ourselves and the truth is not in us.

If we say that we have not sinned, we make him a liar, and his word is not in us.

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 this person.

The one who says [that he] resides in him ought also to walk just as that one walked.

The one who says [he] is in the light and hates his brother is in the darkness until now.

If anyone says, "I love God," and hates his brother, he is a liar, for the one who does not love his brother whom he has seen is not able to love God whom he has not seen.

If anyone should see his brother sinning a sin not [leading] to death, he should ask, and he will grant life to him, to those who sin not [leading] to death. ([There] is a sin [leading] to death; I do not say that he should ask about that.
