We have come to know love by this: that Jesus laid down his life for us; thus we ought to lay down our lives for our fellow Christians.

(See what sort of love the Father has given to us: that we should be called God’s children – and indeed we are! For this reason the world does not know us: because it did not know him.

And we have come to know and to believe the love that God has in us. God is love, and the one who resides in love resides in God, and God resides in him.
