Alma 5

To members of the Church, being a responsible priesthood leader, Alma tells those in Zarahemla -

"...the Spirit saith unto me, yea, crieth unto me with a mighty voice, saying: Go forth and say unto this people—Repent, for except ye repent ye can in nowise inherit the kingdom of heaven." (Book of Mormon | Alma 5:51)

He then explains what it means to repent or that which they are in need of repentance-

"...can ye be puffed up in the pride of your hearts; yea, will ye still persist in the wearing of costly apparel and setting your hearts upon the vain things of the world, upon your riches?
54 Yea, will ye persist in supposing that ye are better one than another; yea, will ye persist in the persecution of your brethren, who humble themselves and do walk after the holy order of God, wherewith they have been brought into this church, having been sanctified by the Holy Spirit, and they do bring forth works which are meet for repentance—
55 Yea, and will you persist in turning your backs upon the poor, and the needy, and in withholding your substance from them?
56 And finally, all ye that will persist in your wickedness..." (Book of Mormon | Alma 5:53 - 56)

He could easily be talking to the people of our day. The consequence is great for he warns -

"...Behold, the ax is laid at the root of the tree; therefore every tree that bringeth not forth good fruit shall be hewn down and cast into the fire, yea, a fire which cannot be consumed, even an unquenchable fire. Behold, and remember, the Holy One hath spoken it." (Book of Mormon | Alma 5:52)

To avoid this terrible consequence, we must become as those -

"...brethren, who humble themselves and do walk after the holy order of God, wherewith they have been brought into this church, having been sanctified by the Holy Spirit, and they do bring forth works which are meet for repentance—" (Book of Mormon | Alma 5:54)

Of these -

"...the names of the righteous shall be written in the book of life, and unto them will I grant an inheritance at my right hand..." (Book of Mormon | Alma 5:58)
