You belong to your father, the devil, and you want to carry out your father's desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies.
NIV
You are of your father, the devil, and it is your will to practice the lusts and gratify the desires [which are characteristic] of your father.
