He who has faith in the Son of God has the witness in himself: he who has not faith in God makes him false, because he has not faith in the witness which God has given about his Son.

And we are certain that the Son of God has come, and has given us a clear vision, so that we may see 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.

Everyone who says openly that Jesus is the Son of God, has God in him and is in God.

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

If we take the witness of men to be true, the witness of God is greater: because this is the witness which God has given about his Son.

We are certain that one who is a child of God will do no sin, but the Son of God keeps him so that he is not touched by the Evil One.
