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

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.

And we have seen and testify that the Father has sent the Son to be the Savior of the world.

If anyone confesses that Jesus is the Son of God, God resides in him and he in God.

And this is the testimony: God has given us eternal life, and this life is in his Son.

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

(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.)

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.

Now this is his commandment: that we believe in the name of his Son Jesus Christ and love one another, just as he gave us the commandment.

In this is love: not that we have loved God, but that he loved us and sent his Son to be the atoning sacrifice for our sins.

If we accept the testimony of men, the testimony of God is greater, because this is the testimony of God that he has testified concerning his Son.

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.

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.

By this the love of God is revealed in us: that God has sent his one and only Son into the world so that we may live through him.

What we have seen and heard we announce to you too, so that you may have fellowship with us (and indeed our fellowship is with the Father and with his Son Jesus Christ).

But if we walk in the light as he himself is in the light, we have fellowship with one another and the blood of Jesus his Son cleanses us from all sin.

As for you, what you have heard from the beginning must remain in you. If what you heard from the beginning remains in you, you also will remain in the Son and in the Father.

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.

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

(See what sort of love the Father has given to us: that we should be called God’s children – and indeed we are! For this reason the world does not know us: because it did not know him.
