God showed Nebuchadnezzar 3 times He is the only God. First through Daniel and Shadrach, Meshach, and Abednego eating the food they are used to for 10 days and the King proving them. He found them far superior. Then through testing the magicians, the sorcerers, all his "wise" and seeing who could find out his dream and then tell him what it meant. God shows Daniel the dream and tells him the meaning. Only a God could do that the king declares. The King then builds a 90 foot statue of himself- Shadrach, Meshach, and Abednego refuse to bow to and worship it. The king is furious and throws them in the fiery furnace. They are accompanied by an angel and come out not even smelling of smoke. God wants all. God shines HIs light through Daniel and his friends, Working miracles! Proving to many He is the only God!
