Shadrach, Meshach, and Abednego refused to worship the visible golden statue. Because they insisted on worshiping the unseen God. For this, Nebuchadnezzar cast them into the fiery furnace.
Does the fiery furnace have a spiritual meaning for us? God made us for love: to love Him and glorify Him in His works. This demands that we ruthlessly separate ourselves from the temptation to love and worship things that fall short of God. Therefore, to believe means living in a kind of fiery furnace: the furnace of divine love, which burns everything impure.
The real God–the invisible, transcendent God Almighty–can send angels to help us. And the angel who accompanied the three young men prefigured the Son of God, Who was to come–the Angel of Great Counsel, the King of Angels.
“If God were your Father, you would love me,” saith the incarnate Christ. Christ gives us the purity that makes living in the furnace endurable. More than endurable: with Christ’s grace, living in the world for the glory of the Father, loving God and nothing less than God—it becomes pure joy. Heaven awaits.
