There is no work that God has made—the sun, moon, stars, and all the world—in which so much of the glory of God appears as in a man who lives quietly in the midst of adversity. That was what convinced the king: he saw that the three children could walk in the midst of the fiery furnace and not be touched (Dan 3:25). By this, the king was mightily convinced that surely their God was the great God indeed. So when a Christian can walk in the midst of fiery trials without his garments being singed and has comfort and joy in the midst of everything—when like Paul in the stocks he can sing, which wrought upon the jailor (Act 16:25-34)—it will convince men, when they see the power of grace in the midst of afflictions. When they can behave themselves in a gracious and holy manner in such afflictions as would make others roar, this is the glory of a Christian!
