Alma Ch40

In this installment of Alma's counsel with Corianton, he speaks about Christ's resurrection and some of what happens to us after death. Everyone goes to their own place to wait for the resurrection when all things will be restored back to a perfect state.
Alma can tell his son is having a hard time comprehending the resurrection, so he clarifies it by saying it won't happen until Christ comes, and only God knows when that time is, but when it does happen the dead will rise again (v1-5). Alma has prayed to know the truth about the time between death and the resurrection, and he found out that the spirits of all men will return to God and be 'sorted' into a state of paradise if they were righteous and a state of outer darkness (or prison) until the resurrection (v6-14). According to Alma, some have called this the first resurrection, but really it isn't a final state of rest because there is the actual resurrection where the soul will be reunited with a perfect body (v15-18).
Neither Alma nor I, nor anyone I know, can tell you in what order the resurrection will come, whether the righteous be first or the first people that died on earth, just no idea (v19). I personally don't think any resurrections besides Christ's has happened, unless you count people who were transfigured like Enoch and the three Nephites, so I also am in the dark on that subject like Alma, but there IS the spirit world after death and before the resurrection and judgment (v20-22). Everyone will be in a perfected body when they are resurrected and after we are judged we will either be with Heavenly Father in His kingdom, or somewhere else if we are unclean and unworthy (v23-26).
