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

And we know that the Son of God has come, and has given us an understanding that we should know him that is true; and we are in him that is true, in his Son Jesus Christ. He is the true God and eternal life.

Whosoever shall confess that Jesus is the Son of God, God abides in him, and he in God.

He that has the Son has life: he that has not the Son of God has not life.

Herein as to us has been manifested the love of God, that God has sent his only begotten 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 the witness of God which he has witnessed concerning his Son.
