It is clear who are the children of God and who are the children of the devil by this—anyone who does not act righteously or love his brother is not of God.
“But love your enemies, and do good, and lend, expecting nothing in return. Then your reward will be great and you will be sons of Elyon, for He is kind to the ungrateful and evil ones.
You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning and does not stand in the truth, because there is no truth in him. Whenever he speaks lies he is just being himself—for he is a liar and the father of lies.
and said, “O you, full of all deceit and trickery, son of the devil, enemy of all righteousness—will you not stop making crooked the straight paths of the Lord?
See how glorious a love the Father has given us, that we should be called God’s children—and so we are! The reason the world does not know us is that it did not know Him.
Loved ones, now we are God’s children; and it has not yet been revealed what we will be. But we do know that when it’s revealed, we shall be like Him, because we will see Him just as He is.
We are from God; whoever knows God listens to us, but whoever is not from God does not listen to us. By this we know the Spirit of truth and the spirit of error.
