King Nebuchadnezzar threw people into the “burning fiery furnace” if they refused to bow down to him. Shadrach, Meshach, and Abed-Nego, however, were not afraid of such threats. They knew the one true God, and that He could deliver them from the inventions of mere men if He so desired.
“For God did not send His Son into the world to condemn the world, but that the world through Him might be saved.” (John 3:17)
God is not like Nebuchadnezzar, He saves humanity from the wages of sin…which is death. He did not create a fiery furnace for those who refused His salvation. He has not given humanity a choice in the matter at all. Just as God saved His Son Jesus from death, Jesus has promised to return and save the rest of humanity from death.
Jesus will then judge humanity in righteousness, not in anger. Humanity will be made into a new creation of immortals, so, humanity does not need to fear death!
"So do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you; I will uphold you with my righteous right hand." (Isaiah 41:10)
"Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid." (John 14:27)
"The Spirit of God, who raised Jesus from the dead, lives in you. And just as God raised Christ Jesus from the dead, He will give life to your mortal bodies by this same Spirit living within you." (Romans 8:11)
