God does not desire suffering as an end in itself, I am sure. But all suffering is so expensive he will not let it be wasted. He will use it for his children’s growth. The first purpose of our lives must be, “Thy kingdom come, thy will be done.” This is never a passive statement of endurance or of mere agreement to submit to whatever happens. It is a positive statement of the will to reach out for that which will bring glory to God. I am also sure that the greatest prayer we can pray is, “Whatever brings the greatest glory to God, I want it, even if it brings suffering and loss to me.”
