…the flame of the fire slew those men that took up Shadrach, Meshach, and Abednego. -Daniel 3:22

The devil is never more devoid of wisdom than when he meddles with God’s people…Did any Christian ever suffer yet by persecution-really suffer by it? Does he ever really lose by it? No; it is quite the reverse. We gain by it. You remember the case of the burning fiery furnace of Shadrach, Meshech, and Abednego, and Nebuchadnezzar’s dealings. You remember he commanded that the furnace should be heated seven times hotter than usual; and he told his brave men, his strongest ones, to take these three men bound and cast them into the furnace. There they go! they have thrown three men bound into the fire; but before they have time to turn back it is said, the heat of the flames slew those men that cast them into the furnace. Nebuchadnezzar said himself, “Did we not cast three bound into the furnace? Behold I see four men loose walking in the midst of the fire, and the fourth is like the Son of God.” Now, just mark these points. Nebuchadnezzar made a great blunder, and heated the fire too hot. That is just what our enemies often do. if they would just speak the truth about us and only tell our imperfections, they would then have enough to do. But, in their endeavours to cast down God’s servants, they heat the fire rather too hot; they make what they say smell, as Rowland Hill said, too much like a lie, therefore, nobody believes them; and instead of doing any hurt, it just kills the men who would have cast us into the fire.

Persecution damages our enemies; it cannot hurt us. Let them still go on; let them still fight; all their arrows fall back upon themselves. And as for aught of evil that is done against us. it is but small and light compared with the damage that is done to their own cause. This, then, is another blessing concerning the furnace-it hurts our enemies though it does not hurt us.~ C.H. Spurgeon
