⁴⁴ For you are the children of your father the devil, and you love to do the evil things he does. He was a murderer from the beginning. He has always hated the truth, because there is no truth in him. When he lies, it is consistent with his character; for he is a liar and the father of lies.

⁴⁷ Anyone who belongs to God listens gladly to the words of God. But you don’t listen because you don’t belong to God.”

⁴ Satan, who is the god of this world, has blinded the minds of those who don’t believe. They are unable to see the glorious light of the Good News. They don’t understand this message about the glory of Christ, who is the exact likeness of God.

⁸ But when people keep on sinning, it shows that they belong to the devil, who has been sinning since the beginning. But the Son of God came to destroy the works of the devil. ⁹ Those who have been born into God’s family do not make a practice of sinning, because God’s life^[a] is in them. So they can’t keep on sinning, because they are children of God. ¹⁰ So now we can tell who are children of God and who are children of the devil. Anyone who does not live righteously and does not love other believers^[b] does not belong to God.

Love One Another

¹¹ This is the message you have heard from the beginning: We should love one another. ¹² We must not be like Cain, who belonged to the evil one and killed his brother. And why did he kill him? Because Cain had been doing what was evil, and his brother had been doing what was righteous. ¹³ So don’t be surprised, dear brothers and sisters,^[c] if the world hates you.

¹⁴ If we love our brothers and sisters who are believers,^[d] it proves that we have passed from death to life. But a person who has no love is still dead. ¹⁵ Anyone who hates another brother or sister^[e] is really a murderer at heart. And you know that murderers don’t have eternal life within them.

¹⁹ We know that we are children of God and that the world around us is under the control of the evil one.
