He who says, "I know him," but does not keep his commandments, is a liar, and the truth is not in him.

he who says he abides in him ought to walk as he walked.

He who says he is in the light and hates his brother is in the darkness still.

He who loves his brother abides in the light, and there is no cause for stumbling in him.

But he 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 write to you, fathers, because you have known him who is from the beginning. I write to you, young men, because you have overcome the evil one.

I wrote to you, little children, because you have known the Father. I wrote to you, fathers, because you have known him who is from the beginning. I wrote to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one.

And the world is passing away, and the lust of it; but he who does the will of God abides forever.

Who is the liar but he who denies that Jesus is the Christ? This is the Antichrist, he who denies the Father and the Son.

No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.

These things I have written to you about those who try to deceive you.

If you know that he is righteous, you know that everyone who does right is born of him.

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

Everyone who commits sin also commits lawlessness; sin is lawlessness.

No one who abides in him sins. No one who sins has either seen him or known him.

Little children, let no one deceive you. He who does right is righteous, just as he is righteous.

He who commits sin is of the devil, for the devil has sinned from the beginning. The reason the Son of God appeared was to destroy the works of the devil.

No one who is of God practices sin, for God's seed remains in him; and he cannot sin, because he has been born of God.

By this it may be seen who are the children of God, and who are the children of the devil: whoever does not do right is not of God, nor he who does not love his brother.

and not be like Cain who was of the evil one and murdered his brother. And why did he murder him? Because his own deeds were evil and his brother's righteous.

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

Anyone who hates his brother is a murderer, and you know that no murderer has eternal life abiding in him.

Now those who keep his commandments abide in him, and he in them. And by this we know that he abides in us, by the Spirit whom he has given us.

You are of God, little children, and have overcome them, because he who is in you is greater than he who is in the world.

We are of God. Whoever knows God listens to us; he who is not of God does not listen to us. By this we know the spirit of truth and the spirit of error.

Beloved, let us love one another, for love is of God; and everyone who loves is born of God and knows God.

He who does not love does not know God, for God is love.

So we know and believe the love God has for us. God is love, and he who abides in love abides in God, and God in him.

There is no fear in love, but perfect love casts out fear, because fear has to do with punishment. And he who fears is not made perfect in love.

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

And this commandment we have from him: that he who loves God must love his brother also.

Everyone who believes that Jesus is the Christ is born of God, and everyone who loves the parent loves the child.

Who is it that overcomes the world but he who believes that Jesus is the Son of God?

This is he who came by water and bloodJesus Christ; not only by water, but by water and blood.

And it is the Spirit who bears witness, because the Spirit is the truth.

He who believes in the Son of God has the testimony in himself. He who does not believe God has made him a liar, because he has not believed in the testimony that God has given of his Son.

He who has the Son has life; he who does not have the Son of God does not have life.

I write these things to you who believe in the name of the Son of God, so that you may know that you have eternal life.

We know that anyone born of God does not sin; but he who was born of God keeps him, and the evil one does not touch him.

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