“If God were unkind enough to answer some of our prayers at once, and in our way, we should be very impoverished Christians.” (D. Martyn Lloyd-Jones, From Fear to Faith: Studies in the Book of Habakkuk – and the Problem of History, page 24)
It is, it seems to me, a far greater test of the depth and legitimacy of faith, to believe this statement as true, than it is to believe that God answers every rightly prayed prayer.
