Alma 34 - 36

Jacob explained the purpose of the Law of Moses and why his people continued to follow it. It was because -

...they believed in Christ and worshiped the Father in his name, and also we worship the Father in his name. And for this intent we keep the law of Moses, it pointing our souls to him; and for this cause it is sanctified unto us for righteousness, even as it was accounted unto Abraham in the wilderness to be obedient unto the commands of God in offering up his son Isaac, which is a similitude of God and his Only Begotten Son." (Book of Mormon Jacob 4:5)

Nephi also said -

"And, notwithstanding we believe in Christ, we keep the law of Moses, and look forward with steadfastness unto Christ, until the law shall be fulfilled." (Book of Mormon 2 Nephi 25:24)

Amulek taught the Zoramites that -

"...it is expedient that there should be a great and last sacrifice, and then shall there be, or it is expedient there should be, a stop to the shedding of blood; then shall the law of Moses be fulfilled..." (Book of Mormon Alma 34:13)

"...For it is expedient that there should be a great and last sacrifice; yea, not a sacrifice of man, neither of beast, neither of any manner of fowl; for it shall not be a human sacrifice; but it must be an infinite and eternal sacrifice." (Book of Mormon Alma 34:10)

A sacrifice of him that is infinite and eternal, for -

"...this is the whole meaning of the law, every whit pointing to that great and last sacrifice; and that great and last sacrifice will be the Son of God, yea, infinite and eternal.
(Book of Mormon Alma 34:14)

"...for according to the great plan of the Eternal God there must be an atonement made, or else all mankind must unavoidably perish; yea, all are hardened; yea, all are fallen and are lost, and must perish except it be through the atonement which it is expedient should be made." (Book of Mormon Alma 34:9)

Amulek testified -

"...I do know that Christ shall come among the children of men, to take upon him the transgressions of his people, and that he shall atone for the sins of the world..." (Book of Mormon Alma 34:8)

And with that -

"...he shall bring salvation to all those who shall believe on his name; this being the intent of this last sacrifice, to bring about the bowels of mercy, which overpowereth justice, and bringeth about means unto men that they may have faith unto repentance.
16 And thus mercy can satisfy the demands of justice, and encircles them in the arms of safety, while he that exercises no faith unto repentance is exposed to the whole law of the demands of justice; therefore only unto him that has faith unto repentance is brought about the great and eternal plan of redemption." (Book of Mormon Alma 34:15 - 16)

Amulek then describes what the Lord expects of those who desire such mercy -

" may God grant unto you, my brethren, that ye may begin to exercise your faith unto repentance, that ye begin to call upon his holy name, that he would have mercy upon you;
18 Yea, cry unto him for mercy; for he is mighty to save.
19 Yea, humble yourselves, and continue in prayer unto him.
20 Cry unto him when ye are in your fields, yea, over all your flocks.
21 Cry unto him in your houses, yea, over all your household, both morning, mid–day, and evening.
22 Yea, cry unto him against the power of your enemies.
23 Yea, cry unto him against the devil, who is an enemy to all righteousness.
24 Cry unto him over the crops of your fields, that ye may prosper in them.
25 Cry over the flocks of your fields, that they may increase.
26 But this is not all; ye must pour out your souls in your closets, and your secret places, and in your wilderness.
27 Yea, and when you do not cry unto the Lord, let your hearts be full, drawn out in prayer unto him continually for your welfare, and also for the welfare of those who are around you." (Book of Mormon Alma 34:17 - 27)

And in addition to -

"...I say unto you, do not suppose that this is all; for after ye have done all these things, if ye turn away the needy, and the naked, and visit not the sick and afflicted, and impart of your substance, if ye have, to those who stand in need—I say unto you, if ye do not any of these things, behold, your prayer is vain, and availeth you nothing, and ye are as hypocrites who do deny the faith.
29 Therefore, if ye do not remember to be charitable, ye are as dross, which the refiners do cast out, (it being of no worth) and is trodden under foot of men." (Book of Mormon Alma 34:28 - 29)

Amulek also warns that time is of the essence -

"...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." (Book of Mormon Alma 34:33)

Why? Because -

"...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.
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...because the Lord hath said he dwelleth not in unholy temples, but in the hearts of the righteous..." (Book of Mormon Alma 34:34 - 36)

And in closing, Amulek exhorts -

"...take upon you the name of Christ; that ye humble yourselves even to the dust, and worship God, in whatsoever place ye may be in, in spirit and in truth; and that ye live in thanksgiving daily, for the many mercies and blessings which he doth bestow upon you...be watchful unto prayer continually, that ye may not be led away by the temptations of the devil, that he may not overpower you, that ye may not become his subjects at the last day; for behold, he rewardeth you no good thing...have patience, and that ye bear with all manner of afflictions; that ye do not revile against those who do cast you out...lest ye become sinners like unto them..." (Book of Mormon Alma 34:38 - 4o)

And finally -

"...have patience, and bear with those afflictions, with a firm hope that ye shall one day rest from all your afflictions." (Book of Mormon Alma 34:41)
