I am a Christian because of that moment on the cross when Jesus, drinking the very dregs of human bitterness, cries out, My God, my God, why hast thou forsaken me? (I know, I know: he was quoting the Psalms, and who quotes a poem when being tortured? The words aren’t the point. The point is he felt human destitution to its absolute degree; the point is that God is with us, not beyond us, in suffering.)
