From Richard Mast

A – 7 Beloved, let us love one another,

B – 7b for love is of God;

C – 8 God is love.

D – 9 In this the love of God was manifested toward us, that God has sent His only begotten Son into the world, that we might live through Him.

C’ – 10 In this is love,

B’ – 11 if God so loved us,

A’ – 11b we also ought to love one another.
