Mosiah 40:11-14
Now, concerning the state of the soul between death and the resurrection—Behold, it hath been made known unto me by an angel, that the spirits of all men, as soon as they are departed from this mortal body, yea, the spirits of all men, whether they be good or evil, are taken home to that God who gave them life. And then shall it come to pass, that the spirits of those which are righteous are received into a state of happiness, which is called paradise, a state of rest, a state of peace, where they shall rest from all their troubles, and from all care, and sorrow, etc. And then shall it come to pass, that the spirits of the wicked, yea, which are evil—for behold, they have no part nor portion of the Spirit of the Lord; for behold, they chose evil works rather than good; therefore the spirit of the devil did enter into them, and take possession of their house—and these shall be cast out into outer darkness; there shall be weeping, and wailing, and gnashing of teeth, and this because of their own iniquity, being led captive by the will of the devil.
Now this is the state of the souls of the wicked, yea, in darkness, and a state of awful, fearful looking for of the fiery indignation of the wrath of God upon them; thus they remain in this state, as well as the righteous in paradise, until the time of their resurrection.
Once our time on this earth is over, our fate for eternity is sealed. We cannot change where we spend eternal life after we die. So make the most of the time you have not and find salvation. You only get one life.
