He that believes on the Son of God has the witness in himself: he that believes not God has made him a liar; because he believes not the witness that God gave of his Son.

These things have I written unto you that believe on the name of the Son of God; that you may know that you have eternal life, and that you may believe on the name of the Son of God.

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

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

He that has the Son has life; and he that has not the Son of God has not life.

In this was manifested the love of God toward us, because God 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 testified of his Son.
