Matthew 13.41-42: "The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth."
Matthew 13.49-50: "So shall it be at the end of the world: the angels shall come forth, and sever the wicked from among the just, And shall cast them into the furnace of fire: there shall be wailing and gnashing of teeth."
with Daniel 3 -- the entire chapter, but especially vss. 26 and 27: Then Nebuchadnezzar came near to the mouth of the burning fiery furnace, and spake, and said, Shadrach, Meshach, and Abednego, ye servants of the most high God, come forth, and come hither. Then Shadrach, Meshach, and Abednego, came forth of the midst of the fire. And the princes, governors, and captains, and the king's counsellers, being gathered together, saw these men, upon whose bodies the fire had no power, nor was an hair of their head singed, neither were their coats changed, nor the smell of fire had passed on them."
Both parties go into a fire: one group suffers, the other doesn't, to the point that there's not even a smell of fire on them. Is it because in one there's nothing to burn, and the other there is?
