Don’t imagine I doubt for a moment that what God sends us must be sent in love and will all be for the best if we have grace to use it so. My mind doesn’t waver on this point; my feelings sometimes do. That’s why it does me good to hear what I believe repeated in your voice—it being the rule of the universe that others can do for us what we cannot do for ourselves and one can paddle every canoe except one’s own. That is why Christ’s suffering for us is not a mere theological dodge but the supreme case of the law that governs the whole world; and when they mocked him by saying, ‘He saved others, himself he connot save,’ [Matthew 27:42; Mark 15:31] they were really uttering, little as they knew it, the ultimate law of the spiritual world.
