Your father is the devil. You belong to him. You want to do what he wants. The devil was a murderer from the beginning. He was always against the truth. There is no truth in him. He is like the lies he tells. Yes, the devil is a liar. He is the father of lies.
There are many people who refuse to obey—people who talk about worthless things and lead other people into the wrong way. I am talking mostly about those people who say that all non-Jewish people must be circumcised. {\cf2\super [6]}
Those people say they know God. But the evil things those people do show that they don’t accept God. They are disgusting people. They refuse to obey and are useless for doing anything good.
A person says, “I am in the light. {\cf2\super [4]} ” But if that person hates his brother or sister \{in Christ\}, then he is still in the darkness (sin).
So the person who lives in Christ does not continue to sin. If a person continues to sin, he has never really understood Christ and has never known Christ.
If a person says, “I love God,” but that person hates his brother or sister \{in Christ\}, then that person is a liar. That person can see his brother, but he hates him. So that person cannot love God, because he has never seen God!
Dear friends, we should love each other, because love comes from God. The person who loves has become God’s child. And so the person who loves knows God.
