But we all suffer. For we all prize and love; and in this present existence of ours, prizing and loving yield suffering. Love in our world is suffering love. Some do not suffer much, though, for they do not love much. Suffering is for the loving. 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
