Therefore, because the king’s command was urgent, and the furnace exceedingly hot, the flame of the fire killed those men who took up Shadrach, Meshach, and Abed-Nego. And these three men, Shadrach, Meshach, and Abed-Nego, fell down bound into the midst of the burning fiery furnace. Then King Nebuchadnezzar was astonished; and he rose in haste and spoke, saying to his counselors, “Did we not cast three men bound into the midst of the fire?” They answered and said to the king, “True, O king.” “Look!” he answered, “I see four men loose, walking in the midst of the fire; and they are not hurt, and the form of the fourth is like the Son of God.” Then Nebuchadnezzar went near the mouth of the burning fiery furnace and spoke, saying, “Shadrach, Meshach, and Abed-Nego, servants of the Most High God, come out, and come here.” Then Shadrach, Meshach, and Abed-Nego came from the midst of the fire. And the satraps, administrators, governors, and the king’s counselors gathered together, and they saw these men on whose bodies the fire had no power; the hair of their head was not singed nor were their garments affected, and the smell of fire was not on them. Nebuchadnezzar spoke, saying, “Blessed be the God of Shadrach, Meshach, and Abed-Nego, who sent His Angel and delivered His servants who trusted in Him, and they have frustrated the king’s word, and yielded their bodies, that they should not serve nor worship any god except their own God! (Dan 3:22-28 NKJ)
Shadrach, Meshach, and Abed-Nego refused to bow to the image or to worship other gods. As a result, they were bound and thrown into the fire. In the fire, they were unbound, unharmed and in fellowship. The flames didn’t hurt them because they had already submitted themselves to the refiner’s fire.
Had they have compromised their faith, though they were ‘free’ they would have been bound. Though they might have escaped the furnace, they would never have escaped or survived God’s refining fire.
If you want to find the Lord, you’ll find him in the places where we are tested the most, never in a place of comfort or compromise.
