Everyone who believes that Jesus is the Christ has been born from God. Whoever loves someone who is a parent loves the child born to the parent.
This is how we know that we love the children of God: when we love God and keep God's commandments.
This is the love of God: we keep God's commandments. God's commandments are not difficult,
because everyone who is born from God defeats the world. And this is the victory that has defeated the world: our faith.
Who defeats the world? Isn't it the one who believes that Jesus is God's Son?
This is the one who came by water and blood: Jesus Christ. Not by water only but by water and blood. And the Spirit is the one who testifies, because the Spirit is the truth.
References for 1 John 5:6
The three are testifying—
the Spirit, the water, and the blood—and the three are united in agreement.
