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

The one who says he resides in God ought himself to walk just as Jesus walked.

The one who says he is in the light but still hates his fellow Christian is still in the darkness.

The one who loves his fellow Christian resides in the light, and there is no cause for stumbling in him.

But the one who hates his fellow Christian is in the darkness, 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, that you have known him who has been from the beginning. I am writing to you, young people, that you have conquered the evil one.

I have written to you, children, that you have known the Father. I have written to you, fathers, that you have known him who has been from the beginning. I have written to you, young people, that you are strong, and the word of God resides in you, and you have conquered the evil one.

And the world is passing away with all its desires, but the person who does the will of God remains forever.

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

Everyone who denies the Son does not have the Father either. The person who confesses the Son has the Father also.

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

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

And everyone who has this hope focused on him purifies himself, just as Jesus is pure).

Everyone who practices sin also practices lawlessness; indeed, 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 Jesus is righteous.

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

Everyone who has been fathered by God does not practice sin, because God's seed resides in him, and thus 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 revealed: Everyone who does not practice righteousness -- the one who does not love his fellow Christian -- is not of God.

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

We know that we have crossed over from death to life because we love our fellow Christians. The one who does not love remains in death.

Everyone who hates his fellow Christian is a murderer, and you know that no murderer has eternal life residing in him.

And the person who keeps his commandments resides in God, and God in him. Now by this we know that God resides in us: by the Spirit he has given us.

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

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 person who knows God listens to us, but 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 person who does not love does not know God, because God is love.

And we have come to know and to believe 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 has to do with punishment. The one who fears punishment has not been perfected in love.

If anyone says "I love God" and yet hates his fellow Christian, he is a liar, because the one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen.

And the commandment we have from him is this: that the one who loves God should love his fellow Christian too.

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

Now who is the person who has conquered the world except the one who believes that Jesus is the Son of God?

Jesus Christ is the one who came by water and blood -- not by the water only, but by the water and 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 this eternal life; the one who does not have the Son of God does not have this eternal life.

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

If anyone sees his fellow Christian committing a sin not resulting in death, he should ask, and God will grant life to the person who commits a sin not resulting in death. There is a sin resulting in death. I do not say that he should ask about that.

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