4 For whatever is born of God is victorious over the world; and this is the victory that conquers the world, even our faith.
5 Who is it that is victorious over [that conquers] the world but he who believes that Jesus is the Son of God [who adheres to, trusts in, and relies on that fact]?
6 This is He Who came by (with) water and blood [His baptism and His death], Jesus Christ (the Messiah)–not by (in) the water only, but by (in) the water and the blood. And it is the [Holy] Spirit Who bears witness, because the [Holy] Spirit is the Truth.
7 So there are three witnesses in heaven: the Father, the Word and the Holy Spirit, and these three are One;
8 and there are three witnesses on the earth: the Spirit, the water, and the blood; and these three agree [are in unison; their testimony coincides].
9 If we accept [as we do] the testimony of men [if we are willing to take human authority], the testimony of God is greater (of stronger authority), for this is the testimony of God, even the witness which He has borne regarding His Son.
10 He who believes in the Son of God [who adheres to, trusts in, and relies on Him] has the testimony [possesses this divine attestation] within himself. He who does not believe God [in this way] has made Him out to be and represented Him as a liar, because he has not believed (put his faith in, adhered to, and relied on) the evidence (the testimony) that God has borne regarding His Son.
