'Love in our world is suffering love. Some do not suffer much, though, for they do not love much. Suffering is for the loving. If I hadn't loved him, there wouldn't be this agony.
This, said Jesus, is the command of the Holy One: "You shall love your neighbor as yourself." In commanding us to love, God invites us to suffer.'
Nicholas Wolterstorff, Lament for a Son, p.89.
