If we say, "We have not sinned," we make Him a liar, and His word is not in us.

He who says, "I have known Him," and does not keep His commandments, is a liar, and the truth is not in him;

Who is the liar, but he that denies that Jesus is the Christ? This is the Anti-Christ, he that denies the Father and the Son.

If anyone says, "I love God," and hates his brother, he is a liar; for he that loves not his brother whom he has seen, cannot love God Whom he has not seen.

He that believes on the Son of God has the witness in himself; he that believes not God has made Him a liar; because he has not believed in the testimony that God testified concerning His Son.
