^12-13 It is true that no human being has ever had a direct vision of God. Yet if we love each other God does actually live within us, and his love grows in us towards perfection. And, as I wrote above, the guarantee of our living in him and his living in us is the share of his own Spirit which he gives us.

Knowing Christ means more love and confidence, less and less fear

^14-16a We ourselves are eye-witnesses able and willing to testify to the fact that the Father did send the Son to save the world. Everyone who acknowledges that Jesus is the Son of God lives in him, and he lives in God. So we have come to know and trust the love God has for us.

^16b-18 God is love, and the man whose life is lived in love does, in fact, live in God, and God does, in fact, live in him. So our love for him grows more and more, filling us with complete confidence for the day when he shall judge all men—for we realise that our life in this world is actually his life lived in us. Love contains no fear—indeed fully-developed love expels every particle of fear, for fear always contains some of the torture of feeling guilty. This means that the man who lives in fear has not yet had his love perfected.

^19-21 Yes, we love him because he first loved us. If a man says, “I love God” and hates his brother, he is a liar. For if he does not love the brother before his eyes how can he love the one beyond his sight? And in any case it is his explicit command that the one who loves God must love his brother too.
