The farthest reach...

'As the farthest reach of our love for each other is loving our enemies,
and as the farthest reach of God's love for us is loving us at our most unlovable and unlovely,
so the farthest reach of our love for God is loving Him when in almost every way that matters we can neither see him nor hear Him, and when He himself might well be our enemy.'
- Frederick Buechner 'A Room Called Remember', on Love.

1 John 4:19 - We love, because He first loved us.
