JC - Chapter 32

As there are similarities in the parable of the pounds and that of the talents, the latter was clearly taught to the Savior's apostles.  I believe what the Savior was trying to teach was -

"For of him unto whom much is given much is required..."  (Doctrine and Covenants | Section 82:3)

From the parable I note that the talents were distributed to the servants -

"...to every man according to his several ability..."  (New Testament | Matthew 25:15)

Yet those that were faithful even with differing abilities, the Master rewarded  -

"Well done, good and faithful servant; thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord."  (New Testament | Matthew 25:23)

The third servant who did nothing, seemed to blame his unfaithfulness on the Master.  Even we supposed less ability, he chose to do nothing.  Consequently...not reward.

Elder Talmage commented -

"The Lord had uttered His last parable. In words of plainness, though suffused with the beauty of effective simile, He impressed upon the listening disciples the certainty of judgment by which the world shall be visited in the day of His appearing. Then shall the wheat be segregated from the tares, and the sheep divided from the goats. “When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory: And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats: And he shall set the sheep on his right hand, but the goats on the left.” Unto those on His right hand the King shall give commendation and blessing, bestowing a rich recompense for their good works, as attested by the hungry they had fed, the thirsty to whom they had given drink, the stranger they had lodged, the naked they had clothed, the sick to whom they had ministered, the prisoners they had visited and encouraged, all of which mercies are accredited to them as having been rendered to their Lord in person. The blessed company, overwhelmed by the plenitude of the King’s bounty, of which they regard themselves as undeserving, will fain disclaim the merit attributed to them; “And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.” [Matt. 13:24–30. ]

Unto them who wait on the left in terrified expectancy, the King shall recount their several deficiencies, in that they had given Him neither food nor drink, shelter nor clothing despite His need; neither had they visited Him though ill, nor ministered unto His wants when He lay in a prison cell. In the desperation of anguish these shall ask when and where they had had such opportunity of comforting Him, and He shall answer, “Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me.” The righteous shall be welcomed with “Come ye blessed of my Father”; the wicked shall hear the awful sentence, “Depart from me ye cursed.” Eternal life is the inestimable reward; everlasting punishment the unfathomable doom."
