Everyone who commits sin is of the devil, for the devil has been sinning from the beginning. The Son of God was revealed for this purpose: to destroy the works of the devil.

God abides in those who confess that Jesus is the Son of God, and they abide in God.

Who is it who conquers the world but the one who believes that Jesus is the Son of God?

Testimony concerning 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 the blood. And the Spirit is the one that testifies, for the Spirit is the truth.

If we receive human testimony, the testimony of God is greater, for this is the testimony of God that he has testified to his Son.

Those who believe in the Son of God have the testimony in their hearts. Those who do not believe in God have made him a liar by not believing in the testimony that God has given concerning his Son.

Whoever has the Son has life; whoever does not have the Son of God does not have life.

Epilogue

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.

And we know that the Son of God has come and has given us understanding so that we may 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.
