They were thrown into the fire, and by his amazement, the king saw four men walking around in the fire, yet there were only three men thrown into it. There was an angel of God walking around inside the fire that was protecting them. They all walked out of the fire without a burn mark or even the slightest smell of smoke on their clothing. Shadrach, Meshach, and Abed- Nego had that much faith that God would deliver them from King Nebuchadnezzar.(Daniel 3) If we did not have faith in God, than we would have faith in ourselves. If that were to happen, than the world would have so many more problems than we already have. We should be thankful that God gave us the knowledge of faith in Him to deliver us from our problems. .
Faith is what the Bible describes in Hebrews 11:1 as the "Substance of things hoped for, the evidence of things not seen." This suggests that even though we cannot see something like the wind, we should believe that it is there. The Bible is probably the best source to discover what faith is supposed to be. (Hebrews 11:1) In the book of Matthew, several examples of faith are given. Matthew 8:5-13 says, "Now when Jesus had entered Capernaum, a centurion came to Him, pleading with Him, saying, "Lord, my servant is lying at home paralyzed and dreadfully tormented." And Jesus said to him, "I will come and heal him." The centurion answered and said "Lord, I am not worthy that You should come under my roof. But only speak a word and my servant will be healed. For I also am a man under authority, having soldiers under me. And I say to this one, "Go," and he goes, and "Come" to another and he comes, and to my servant, "Do this" and he does it." When Jesus heard the man he marveled and said to those who followed, "Assuredly, I say to you, I have not found such great faith, not even in Israel! And I say to you that many will come from the east and west, and sit down with Abraham, Isaac, and Jacob in the kingdom of heaven.
