Your father is the devil, and you love to follow your father's evil desires. He was a murderer from the beginning. He never stood for the truth, because there is no truth in him. When he lies he reveals his true character, for he's a liar and the father of lies.
Anyone who says, “I love God,” but hates a Christian brother or sister, is a liar. Anyone who doesn't love a brother whom they can see, can't love God whom they can't see.
