We have come to know love by this: ¹  that Jesus ²  laid down ³  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 ¹  we should be called God’s children – and indeed ²  we are! ³  For this reason ⁴  the world does not know us: because it did not know him. ⁵ 

And we have come to know and to believe ¹  the love that God has in us. ²  God is love, and the one who resides ³  in love resides in God, and God resides in him.
