Nebuchadnezzar wanted them really dead. So he heated up the executioner’s furnace seven times the normal heat. Even the guards who threw in Shadrach, Meshach, and Abednego died. Talk about… mmm, overkill.
Even so, those three Jews, guilty of not bowing to the king’s idol, didn’t flinch. With great impending disaster bearing down upon them, they stayed faithful. They would only pray and believe in God. They wouldn’t do lip service to appease the wrathful king.
In the end, constancy won. King Nebuchadnezzar leaped to his feet in amazement and asked his advisers, “Weren’t there three men that we tied up and threw into the fire?” They replied, “Certainly, O king.” He said, “Look! I see four men walking around in the fire, unbound and unharmed, and the fourth looks like a son of the gods.” — Dan. 3:24-25 NIV.
After that, the three Jews walked free. Good ole Neb learned not to mess with the One True God. And a decree was issued giving testimony throughout his empire. It pays to remain steadfast, to remain unbowed before the world’s idols despite intense pressure.
