Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the Father loves the child
born of Him.
By this we know that we love the children of God, when we love God and follow His commandments.
For this is the love of God, that we keep His commandments; and His commandments are not burdensome.
For whoever has been born of God overcomes the world; and this is the victory that has overcome the world: our faith.
Who is the one who overcomes the world, but the one who believes that Jesus is the Son of God?
This is the One who came by water and blood, Jesus Christ; not with the water only, but with the water and with the blood. It is the Spirit who testifies, because the Spirit is the truth.
For there are three that testify:
the Spirit and the water and the blood; and the three are in agreement.
If we receive the testimony of people, the testimony of God is greater; for the testimony of God is this, that He has testified concerning His Son.
The one who believes in the Son of God has the testimony in himself; the one who does not believe God has made Him a liar, because he has not believed in the testimony that God has given concerning His Son.
And the testimony is this, that God has given us eternal life, and this life is in His Son.
