He who says he is in the light, and hates his brother, is in the darkness until now.

Who is the liar but he who denies that Jesus is the Christ? He is the antichrist who denies the Father and the Son.

Whoever denies the Son has not the Father either; he who confesses the Son has the Father also.

These things have I written to you concerning those who lead you astray:

If ye know that he is righteous, know that every one who practises righteousness is begotten of him.

In this are manifest the children of God and the children of the devil. Whoever does not practise righteousness is not of God, and he who does not love his brother.

We know that we have passed from death to life, because we love the brethren. He who does not love his brother abides in death.

We are of God; he that knows God hears us; he who is not of God does not hear us. From this we know the spirit of truth and the spirit of error.

If any one say, I love God, and hate his brother, he is a liar: for he that loves not his brother whom he has seen, how can he love God whom he has not seen?

Who is he that gets the victory over the world, but he that believes that Jesus is the Son of God?

These things have I written to you that ye may know that ye have eternal life who believe on the name of the Son of God.
