Zeezrom asks Amulek, "Shall [God] save his people in their sins?" and Amulek says, basically, "no" (see Alma 11: 34-37) (emphasis added). This caused Zeezrom to spurn Amulek, who repeated his answer,
And I say unto you again that he cannot save them in their sins; for I cannot deny his word, and he hath said that no unclean thing can inherit the kingdom of heaven; therefore, how can ye be saved, except ye inherit the kingdom of heaven? Therefore, ye cannot be saved in your sins (Alma 11: 37).Furthermore, the Savior Himself spoke of His mission among mankind,
Behold, I have come unto the world to bring redemption unto the world, to save the world from sin (3 Nephi 9: 21) (emphasis added).He went on to say,
Therefore, whoso repenteth and cometh unto me as a little child, him will I receive, for of such is the kingdom of God. Behold, for such I have laid down my life, and have taken it up again; therefore repent, and come unto me ye ends of the earth, and be saved (3 Nephi 9: 22).Indeed, "the kingdom of God is not filthy" (1 Nephi 15: 34), yet "all have sinned, and come short of the glory of God" (Romans 3: 23). So how do "inherit the kingdom of heaven," if we've all fallen short?
Moroni and Nephi give us the key to overcoming our sin, through the Savior.
Said Moroni:
Yea, come unto Christ, and be perfected in him, and deny yourselves of all ungodliness; and if ye shall deny yourselves of all ungodliness, and love God with all your might, mind and strength, then is his grace sufficient for you, that by his grace ye may be perfect in Christ (Moroni 10: 32).Or, as Nephi so succinctly put it,
[B]elieve in Christ, and [] be reconciled to God; for we know that it is by grace that we are saved, after all we can do (2 Nephi 25: 23) (emphasis added).
