But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus Christ, his Son, cleanses us from all sin.
And then finally, in chapter 4, verse 1Jo 1:20 , "If a man says, I love God, (and a lot of people make that claim, "I love God") and hates his brother, he is a liar." So it's not what I say that counts; what I say can be deceptive. I can even deceive myself. And to say that I love God is a glorious thing, but if I hate my brother, then that's a lie.
