The one who says "I have come to know him," and does not keep his commandments is a liar, and the truth is not in this person.

But the one who hates his brother is in the darkness, and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.

And the world is passing away, and its desire, but the one who does the will of God remains {forever}.

Everyone who denies the Son does not have the Father [either]; the one who confesses the Son has the Father also.

See what sort of love the Father has given to us: that we should be called children of God, and we are! Because of this the world does not know us: because it did not know him.

Everyone who resides in him does not sin. Everyone who sins has neither seen him nor known him.

Everyone who is fathered by God does not practice sin, because his seed resides in him, and [he is] not able to sin, because he has been fathered by God.

By this the children of God and the children of the devil are evident: everyone who does not practice righteousness is not of God, namely, the one who does not love his brother.

We know that we have passed over from death to life because we love the brothers. The one who does not love remains in death.

Everyone who hates his brother is a murderer, and you know that every murderer does not have eternal life residing in him.

But whoever has the world's material possessions and observes his brother {in need} and shuts his heart against him, how does the love of God reside in him?

Dear friends, if our heart does not condemn [us], we have confidence before God,

and every spirit that does not confess Jesus is not from God, and this is the [spirit] of the antichrist, [of] which you have heard that it is coming, and now it is already in the world.

We are from God. The one who knows God listens to us; whoever is not from God does not listen to us. By this we know the Spirit of truth and the spirit of deceit.

The one who does not love does not know God, because God is love.

If anyone says, "I love God," and hates his brother, he is a liar, for the one who does not love his brother whom he has seen is not able to love God whom he has not seen.

(The one who believes in the Son of God has the testimony in himself. The one who does not believe God has made him a liar, because he has not believed in the testimony that God has testified concerning his Son.)

The one who has the Son has the life; the one who does not have the Son of God does not have the life.

We know that everyone who is fathered by God does not sin, but the one fathered by God, he protects him, and the evil one does not touch him.
