3 Nephi 24

In modern day, the Lord said -

"...there are many called, but few are chosen. And why are they not chosen?
35 Because their hearts are set so much upon the things of this world, and aspire to the honors of men..."  (Doctrine and Covenants Section 121:34 - 35)

Having given these words to Malachi, the Savior again has called his covenant people and then outlines the condition of being chosen -

"...Return unto me and I will return unto you, saith the Lord of Hosts..."  (Book of Mormon 3 Nephi 24:7)

Those whose hearts are more set upon the things of this world seem to justify their actions, whose -

"...words have been stout against me, saith the Lord..."  (Book of Mormon 3 Nephi 24:13)

To which they respond -

"...What have we spoken against thee?..."  (Book of Mormon 3 Nephi 24:13)

The Lord then answers -

"Ye have said: It is vain to serve God, and what doth it profit that we have kept his ordinances and that we have walked mournfully before the Lord of Hosts?
15 And now we call the proud happy; yea, they that work wickedness are set up; yea, they that tempt God are even delivered."  (Book of Mormon  3 Nephi 24:14 - 15)

In other words, why should we being called keep the commandments.  Look! There are those that don't and they are doing just fine.  The Lord then answers the blessing or tender mercies that will come to those that obey and are faithful -

"Then they that feared the Lord spake often one to another, and the Lord hearkened and heard; and a book of remembrance was written before him for them that feared the Lord, and that thought upon his name.
17 And they shall be mine, saith the Lord of Hosts, in that day when I make up my jewels; and I will spare them as a man spareth his own son that serveth him."  (Book of Mormon  3 Nephi 24:16 - 17)

This is the blessing that will come to those that are chosen.
