1 John 1:10; 1 John 2:4; 1 John 2:22; 1 John 4:20; 1 John 5:10
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 him;
Who is the liar but the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son.
If someone 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, cannot love God whom he has not seen.
The one who believes in the Son of God has the testimony in himself; the one who does not believe God has made Him a liar, because he has not believed in the testimony that God has given concerning His Son.
