Daniel 3

"We believe that through the Atonement of Christ, all mankind may be saved, by obedience to the laws and ordinances of the Gospel." (Pearl of Great Price | Articles of Faith 1:3)

We read in the days of King Nebuchadnezzar, when -

"Shadrach, Meshach, and Abed-nego, answered and said to the king, O Nebuchadnezzar, we are not careful to answer thee in this matter.
17 If it be so, our God whom we serve is able to deliver us from the burning fiery furnace, and he will deliver us out of thine hand, O king.
18 But if not, be it known unto thee, O king, that we will not serve thy gods, nor worship the golden image which thou hast set up." (Old Testament | Daniel 3:16 - 18)

...that -

"Then was Nebuchadnezzar full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abed-nego: therefore he spake, and commanded that they should heat the furnace one seven times more than it was wont to be heated.
20 And he commanded the most mighty men that were in his army to bind Shadrach, Meshach, and Abed-nego, and to cast them into the burning fiery furnace.
21 Then these men were bound in their coats, their hosen, and their hats, and their other garments, and were cast into the midst of the burning fiery furnace." (Old Testament | Daniel 3:19 - 21)

"Then Nebuchadnezzar the king was astonied, and rose up in haste, and spake, and said unto his counsellors, Did not we cast three men bound into the midst of the fire? They answered and said unto the king, True, O king.
25 He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God." (Old Testament | Daniel 3:24 - 25)

What is interesting is the words "they have no hurt". The story continues that they -

"...came forth of the midst of the fire.
27 And the princes, governors, and captains, and the king's counsellors, 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." (Old Testament | Daniel 3:26 - 27)

In other words, there was no harm done to them or they were "saved". All of us will pass through fiery tribulaton or challenges, some maybe "seven times" more than others. But nonetheless, if we have faith in Jesus Christ by demonstrating obedience to the laws and ordinances of the gospel, we may also be "saved" or receive no harm whether by death or by living.
