In this the children of God and the children of the devil are revealed: Whoever does not live in righteousness is not of God, nor is the one who does not love his brother.
But love your enemies, and do good, and lend, hoping for nothing in return. Then your reward will be great, and you will be the sons of the Highest. For He is kind to the unthankful and the evil.
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. When he lies, he speaks from his own nature, for he is a liar and the father of lies.
Consider how much love the Father has given to us, that we should be called children of God. Therefore the world does not know us, because it did not know Him.
Beloved, now are we children of God, and it has not yet been revealed what we shall be. But we know that when He appears, we shall be like Him, for we shall see Him as He is.
We are of God, and whoever knows God listens to us. Whoever is not of God does not listen to us. This is how we know the spirit of truth and the spirit of error.
