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.

¹⁰ Then he said, “You son of the devil, full of every sort of deceit and fraud, and enemy of all that is good! Will you never stop perverting the true ways of the Lord?

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.

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.

³ But I fear that somehow your pure and undivided devotion to Christ will be corrupted, just as Eve was deceived by the cunning ways of the serpent.

⁹ This great dragon—the ancient serpent called the devil, or Satan, the one deceiving the whole world—was thrown down to the earth with all his angels.

The Defeat of Satan

⁷ When the thousand years come to an end, Satan will be let out of his prison. ⁸ He will go out to deceive the nations—called Gog and Magog—in every corner of the earth. He will gather them together for battle—a mighty army, as numberless as sand along the seashore. ⁹ And I saw them as they went up on the broad plain of the earth and surrounded God’s people and the beloved city. But fire from heaven came down on the attacking armies and consumed them.

¹⁰ Then the devil, who had deceived them, was thrown into the fiery lake of burning sulfur, joining the beast and the false prophet. There they will be tormented day and night forever and ever.

⁴¹ No, you are imitating your real father.”

They replied, “We aren’t illegitimate children! God himself is our true Father.”

³⁸ I am telling you what I saw when I was with my Father. But you are following the advice of your father.”

⁶ And I remind you of the angels who did not stay within the limits of authority God gave them but left the place where they belonged. God has kept them securely chained in prisons of darkness, waiting for the great day of judgment.
