If we live faithfully and truthfully in God, there is no weapon that shall prosper against us. The devil's words and trickery will be of no threat. The fire that King Nebuchadnezzar threw the bound Radshack, Meshach, and Abednego into did not hurt the brothers as they were untied and protected by the living God. Despite being thrown into the fires of all of our fears, whether that be failure, divorce, or standing up to a person of power, God is still the living God and he is good.
