In Daniel 3:25 (TNIV), King Nebuchadnezzar was looking inside the blazing furnace into which he has just tossed Shadrach, Meshach, and Abednego, because they wouldn't disobey God and worship a gold image that King Nebuchadnezzar had made. All of a sudden, the king noticed something strange: "Look! I see four men walking around in the fire, unbound and unharmed, and the fourth looks like a son of the gods."
King Nebuchadnezzar had only thrown three men into the seven-times-hotter furnace, but now he saw four. And the fourth didn't really look like a man at all.
King Nebuchadnezzar was a witness to the fact that when we are thrown into the blast furnaces of life, we are never alone. God is always there with us.
Whatever your "furnace" may be today, whatever trial, tribulation, injustice, disaster, persecution, suffering, separation, break up, bad news, tension, stress, anxiety, or preoccupation is causing you to feel the flames of life as they lick up against your face, always remember that you are never in the furnace alone. God is with you, just as He was with Shadrach, Meshach, and Abednego. He will fight the flames for you. He will help you from being singed. Always take refuge in Him, and let Him protect you, during the times when you find yourself in the furnace of life.
