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.

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.

Whoever confesses that Jesus is the Son of God, God remains in him, and he in God.

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

By this God's love was revealed in us, that God has sent his one and only Son into the world that we might live through him.

If we receive the witness of men, the witness of God is greater; for this is God's testimony that he has testified concerning his Son.
