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.

The one who says [that he] resides in him ought also to walk just as that one walked.

The one who says [he] is in the light and hates his brother is in the darkness until now.

The one who loves his brother resides in the light, and [there] is no cause for stumbling in him.

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.

I am writing to you, fathers, because you have known the [One who is] from the beginning. I am writing to you, young men, because you have conquered the evil one.

I have written to you, children, because you have known the Father. I have written to you, fathers, because you have known the [One who is] from the beginning. I have written to you, young men, because you are strong, and the word of God resides in you, and you have conquered the evil one.

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

Who is the liar except the one who denies that Jesus is the Christ? This person is the antichrist, the one who denies the Father and the Son.

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

These [things] I have written to you concerning the ones who are trying to deceive you.

If you know that he is righteous, you know that everyone who practices righteousness has been fathered by him.

And everyone who has this hope in him purifies himself, just as that one is pure.

Everyone who practices sin also practices lawlessness, and sin is lawlessness.

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

Little children, let no one deceive you: the one who practices righteousness is righteous, just as that one is righteous.

The one who practices sin is of the devil, because the devil has been sinning from the beginning. For this [reason] the Son of God was revealed: in order to destroy the works of the devil.

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.

not as Cain, who was of the evil one and violently murdered his brother. And {for what reason} did he violently murder him? Because his deeds were evil and the [deeds] of his brother [were] righteous.

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.

And the one who keeps his commandments resides in him, and he in him. And by this we know that he resides in us: by the Spirit whom he has given to us.

You are from God, little children, and have conquered them, because the one [who is] in you is greater than the one [who is] 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.

Dear friends, let us love one another, because love is from God, and everyone who loves has been fathered by God and knows God.

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

And we have come to know and have believed the love that God has in us. God is love, and the one who resides in love resides in God, and God resides in him.

[There] is no fear in love, but perfect love drives out fear, because fear includes punishment, and the one who is afraid has not been perfected in 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.

And this [is] the commandment we have from him: that the one who loves God should love his brother also.

Everyone who believes that Jesus is the Christ has been fathered by God, and everyone who loves {the father} also loves the [child] fathered by him.

because everyone who is fathered by God conquers the world.

Now who is the one who conquers the world except the one who believes that Jesus is the Son of God?

This is the one who came by water and blood--Jesus Christ, not with the water only, but with the water and with the blood. And the Spirit is the one who testifies, because the Spirit is the truth.

(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.

These [things] I have written to you who believe in the name of the Son of God, in order that you may know that you have eternal life.

If anyone should see his brother sinning a sin not [leading] to death, he should ask, and he will grant life to him, to those who sin not [leading] to death. ([There] is a sin [leading] to death; I do not say that he should ask about that.

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.

And we know that the Son of God has come and has given us understanding, in order that we may know the one who is true, and we are in the one who is true, in his Son Jesus Christ. This one is the true God and eternal life.
