Men will never become great in divinity until they become great in suffering. ‘Ah!’ said Luther, ‘affliction is the best book in my library;’ and let me add, the best leaf in the book of affliction is that blackest of all the leaves, the leaf called heaviness, when the spirit sinks within us, and we cannot endure as we could wish. And yet again; this heaviness is of essential use to a Christian, if he would do good to others.... There are none so tender as those who have been skinned themselves. Those who have been in the chamber of affliction know how to comfort those who are there. Do not believe that any man will become a physician unless he walks the hospitals; and I am sure that no one will become a divine, or become a comforter, unless he lies in the hospital as well as walks through it, and has to suffer himself.
Mark then, Christian, Jesus does not suffer so as to exclude your suffering. He bears a cross, not that you may escape it, but that you may endure it. Christ exempts you from sin, but not from sorrow. Remember that, and expect to suffer.
Israel gained by education. The Lord was not going to lead a mob of slaves into Canaan, to go and behave like slaves there. They had to be tutored. The wilderness was the Oxford and Cambridge for God’s students. There they went to the University, and he taught and trained them, and they took their degree before they entered into the promised land. There is no University for a Christian like that of sorrow and trial. [all ten quotations]
