In Alma 40, we learn that the spirits of all men - good or evil - are taken to a spirit world after death where they are in a paradise of peace and rest or where they are tormented by the lives they have led as they await resurrection and judgment.
There is an interesting statement Alma makes in passing: "all is as one day with God, and time only is measured unto men." (v. 8) For God, all things are present. He knows all things, and in his omniscience, there is no past, present, or future. We measure the passing seconds, minutes, hours, days, and years. But our lives are very short windows in the timeline of eternity. If we had some of that eternal perspective, we might live our short earthly lives differently. Amulek taught (Alma 34):
32 For behold, this life is the time for men to prepare to meet God; yea, behold the day of this life is the day for men to perform their labors.
33 And now, as I said unto you before, as ye have had so many witnesses, therefore, I beseech of you that ye do not procrastinate the day of your repentance until the end; for after this day of life, which is given us to prepare for eternity, behold, if we do not improve our time while in this life, then cometh the night of darkness wherein there can be no labor performed.
We should use the day of this life that we have been given to prepare for eternity.
