@Charles Perkins :
Here's what I see when I read the passage...
4) Whatosever is born of God ( believers ), overcomes the world. It is our faith that does the overcoming.
5) The question is asked, "who is he that overcomes the world?", but he that believes that Jesus is the Son of God.
6) This is He that came by water and blood...Jesus Christ. Not by water only, but by both water and blood. And it is the Spirit that bears witness, because the Spirit is truth.
Putting a few pieces together, I see that Jesus also said that He is the way, the truth and the life ( John 14:6 ).
So if the Spirit is truth, and the Son is truth, then they are both together, the truth.
7) There are three that bear record in Heaven...the Father, the Son and the Holy Ghost...these three, are One.
One in spirit, one in mind, one in agreement.
8) There are three that bear witness in earth...the Spirit, the water and the blood, and these three agree in one.
9) If we ( believers ) receive the witness ( words ) of men, then the witness ( word ) of God is greater..for this ( what follows in verse 10 ) is the witness of God which He has testified of ( from or by ) His Son:
10) He that believes that Jesus is the Son of God, has the Witness ( Holy Spirit ) in himself...he that does not believe God has made Him a liar, because he does not believe the record ( Scriptures ) that God gave "of ( by or from ) His Son.
11) This is the "record" ( truth by both His Son, verbally, and Scripturally ), that God has given to the believer eternal life, and this life is "in" His Son.
12) He that has the Son has life, and he that does not have the Son, does not have life.
The Father is God, the Son / Word ( see John 1 and many other passages, some where Jesus declares that, "before Abraham was, I AM ) is God. and the Spirit is God.
I hope that helps, my friend.
