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

he who says he remains in him ought himself also to walk just like he walked.

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

He who loves his brother remains in the light, and there is no occasion 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 am writing to you, fathers, because you know him who is from the beginning. I write to you, young men, because you have overcome the evil one. I write to you, little children, because you know the Father.

I have written to you, fathers, because you know him who is from the beginning. I have written to you, young men, because you are strong, and the word of God remains in you, and you have overcome the evil one.

The world is passing away with its lusts, but he who does God's will remains 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.

Whoever denies the Son, the same does not have the Father. He who confesses the Son has the Father also.

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

If you know that he is righteous, you know that everyone also who practices righteousness is born of him.

Everyone who has this hope set on him purifies himself, even as he is pure.

Everyone who sins also commits lawlessness. Sin is lawlessness.

Little children, let no one lead you astray. He who does righteousness is righteous, even as he is righteous.

He who sins is of the devil, for the devil has been sinning from the beginning. To this end the Son of God was revealed, to destroy the works of the devil.

In this the children of God are revealed, and the children of the devil. Whoever does not do righteousness is not of God, neither is he who does not love his brother.

unlike Cain, who was of the evil one, and killed his brother. Why did he kill him? Because his works were evil, and his brother's righteous.

We know that we have passed out of death into life, because we love the brothers. He who does not love remains in death.

He who keeps his commandments remains in him, and he in him. By this we know that he remains in us, by the Spirit which he gave us.

By this you know the Spirit of God: every spirit who confesses that Jesus Christ has come in the flesh is of God,

and every spirit who does not confess Jesus is not of God; and this is that of the antichrist, of whom you have heard that it comes. Now it is in the world already.

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

We are of God. He who 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.

We know and have believed the love which God has for us. God is love, and he who remains in love remains in God, and God remains in him.

There is no fear in love; but perfect love casts out fear, because fear has punishment. He who fears is not made perfect in love.

If a man 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.

This commandment we have from him, that he who loves God should also love his brother.

Whoever believes that Jesus is the Christ is born of God. Whoever loves the Father also loves the child who is born of him.

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

This is he who came by water and blood, Jesus Christ; not with the water only, but with the water and the blood. It is the Spirit who testifies, because the Spirit is the truth.

For there are three who testify:

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 concerning his Son.

He who has the Son has the life. He who does not have God's Son does not have the life.

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

If anyone sees his brother sinning a sin not leading to death, he shall ask, and God will give him life for those who sin not leading to death. There is a sin leading to death. I do not say that he should make a request concerning this.

We know that whoever is born of God does not sin, but he who was born of God protects him, and the evil one does not touch him.

We know that the Son of God has come, and has given us an understanding, that we know him who is true, and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life.
