You belong to your father, the devil. You want to obey your father’s wishes. From the beginning, the devil was a murderer. He has never obeyed the truth. There is no truth in him. When he lies, he speaks his natural language. He does this because he is a liar. He is the father of lies.
Many people refuse to obey God. All they do is talk about things that mean nothing. They try to fool others. No one does these things more than the circumcision group.
They claim to know God. But their actions show they don’t know him. They are hated by God. They refuse to obey him. They aren’t fit to do anything good.
Suppose someone claims to love God but hates a brother or sister. Then they are a liar. They don’t love their brother or sister, whom they have seen. So they can’t love God, whom they haven’t seen.
