As members of The Church of Jesus Christ of Latter-day Saints, we have a special understanding of the eternal nature of our souls. We know that we had a premortal existence. We understand that we will live a post mortal life of infinite duration and that we determine the kind of life it will be by our thoughts and actions in mortality. Mortality is very brief but immeasurably important.
That understanding helps us to make wise decisions in the many choices of our daily lives. Seeing life from an eternal perspective helps us focus our limited mortal energies on the things that matter most. We know that death is a necessary transition. It will come sooner or later to each of us. Our mortal bodies will return to earth, and our spirits will return to the spirit world. By virtue of the Savior's atoning sacrifice, we all will be resurrected. Each of us will stand before the judgment bar of the great Jehovah and be rewarded according to our deeds in mortality. If we make every earthly decision with this judgment in mind, we will have used our mortal probation wisely and its days will give us peace in this life and eternal life in the world to come.
