By this the children of God and the children of the devil are revealed: Everyone who does not practice righteousness – the one who does not love his fellow Christian – is not of God.
But love your enemies, and do good, and lend, expecting nothing back. Then your reward will be great, and you will be sons of the Most High, because he is kind to ungrateful and evil people.
You people are from your father the devil, and you want to do what your father desires. He was a murderer from the beginning, and does not uphold the truth, because there is no truth in him. Whenever he lies, he speaks according to his own nature, because he is a liar and the father of lies.
and said, “You who are full of all deceit and all wrongdoing, you son of the devil, you enemy of all righteousness – will you not stop making crooked the straight paths of the Lord?
(See what sort of love the Father has given to us: that we should be called God’s children – and indeed we are! For this reason the world does not know us: because it did not know him.
Dear friends, we are God’s children now, and what we will be has not yet been revealed. We know that whenever it is revealed we will be like him, because we will see him just as he is.
We are from God; the person who 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 deceit.
