John 8:44
The devil is the father you are sprung from, and you want to carry out your father's wishes. He was a murderer from the first, and he has nothing to do with the truth, for there is no truth in him. When he tells a lie, he speaks in his true character, for he is a liar and the father of them.

Whoever hates his brother is a murderer, and you know that no murderer can have eternal life remain in his heart.
