He who professes to know Him, and yet does not obey His commands, is a liar, and the truth has no place in his heart.

But he who hates his brother man is in darkness and is walking in darkness; and he does not know where he is going--because the darkness has blinded his eyes.

And the world, with its cravings, is passing away, but he who does God's will continues for ever.

As for you, let the teaching which you have received from the very beginning continue in your hearts. If that teaching does continue in your hearts, you also will continue to be in union with the Son and with the Father.

See what marvellous love the Father has bestowed upon us--that we should be called God's children: and that is what we are. For this reason the world does not recognize us--because it has not known Him.

By this we can distinguish God's children and the Devil's children: no one who fails to act righteously is a child of God, nor he who does not love his brother man.

and that no spirit is from God which does not acknowledge this about Jesus. Such is the spirit of the anti-Christ; of whose coming you have heard, and it is already in the world.

The man who is beginning to know God listens to us, but he who is not a child of God does not listen to us. By this test we can distinguish the Spirit of truth from the spirit of error.

If any one says that he loves God, while he hates his brother man, he is a liar; for he who does not love his brother man whom he has seen, cannot love God whom he has not seen.

He who believes in the Son of God has the testimony in his own heart: he who does not believe God has made Him a liar, in that he has refused to accept the testimony which God has given about His Son.
