He that believes on the Son of God has the testimony in himself; he that believes not God has made him a liar, because he has not believed in the testimony which God has testified concerning his Son.

And we know that the Son of God has come, and has given us understanding that we may know the true One; and we are in the true One, in his Son Jesus Christ; this is the true God, and eternal life.

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

The love of God was manifested to us in this; that God has sent his only Son into the world that we may live through him.

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