5. They belong to the world; accordingly, their teaching belongs to the world, and the world listens to them.
6. We belong to God, and anyone who knows God listens to us, while anyone who does not belong to God refuses to hear us. This is how we know the spirit of truth and the spirit of deceit.
7. Beloved, let us love one another, because love is of God; everyone who loves is begotten by God and knows God.
8. Whoever is without love does not know God, for God is love.
9. In this way the love of God was revealed to us: God sent his only Son into the world so that we might have life through him.
10. In this is love: not that we have loved God, but that he loved us and sent his Son as expiation for our sins.
11. Beloved, if God so loved us, we also must love one another.
12. No one has ever seen God. Yet, if we love one another, God remains in us, and his love is brought to perfection in us.
