Alma 34:31 - 34:35
Alma 34: 31 Yea, I would that ye would come forth and harden not your hearts any longer; for behold, now is the time and the day of your salvation; and therefore, if ye will repent and harden not your hearts, immediately shall the great plan of redemption be brought about unto you.
It is Amulek’s fervent wish that his listeners put aside the doctrines of the Zoramites and come back into the fold of the gospel and let the atonement work in their lives. Now is the time, he says, for all his hearers to start working out their salvation before it is too late.
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.
Now is the time to do so. This is the purpose of life to get ready for the next one.
Alma 34: 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.
Amulek reiterates again. His listeners have had many witnesses beside what he and Alma have to preaching to them. Do not put it off. If they do not do so now, it might be too late at some time in the future when they get the desire to do so. if they do not do it now and they die in their sinful state, it will be too late to invoke the atonement on their behalf.
Alma 34: 34 Ye cannot say, when ye are brought to that awful crisis, that I will repent, that I will return to my God. Nay, ye cannot say this; for that same spirit which doth possess your bodies at the time that ye go out of this life, that same spirit will have power to possess your body in that eternal world.
There is no option to repent when they are nearing their judgment day. One cannot continue down the path of sin and think they can repent when they see the end coming. The problem is that the propensity to sin will continue in the world to come, if you do not repent while you still can. If you go out of this life enjoying sin, you will want to continue in the world to come.
However there you can’t indulge yourself in sinful acts. You will not have a body to do so.
Alma 34: 35 For behold, if ye have procrastinated the day of your repentance even until death, behold, ye have become subjected to the spirit of the devil, and he doth seal you his; therefore, the Spirit of the Lord hath withdrawn from you, and hath no place in you, and the devil hath all power over you; and this is the final state of the wicked.
So if one thinks he can wait until the just before death to repent, he is sadly mistaken. One will have become so sinful that they lose the power to repent. They come followers of satan. The Spirit of the Lord cannot make headway in one’s life because one has chosen to follow satan. Satan now become their leader and guide.
