Declaring repentance

In section 18 of the book Doctrine and Covenants Oliver Cowdery has inquired of the Lord regarding a promised event that has yet to occur.  That event is the bestowal of the Melchizedek Priesthood  When they were ordained to the Aaronic Priesthood, he and Joseph were promised this latter greater priesthood, and Oliver seems anxious to obtain this great blessing.  Interestingly, the revelation contained in section 18 says nothing about when they will receive it.  In fact without the section heading one would hardly know it had anything to do with the the Melchizedek Priesthood at all.  Instead Oliver is counseled to rely upon the scriptures for answers (vs. 2-5), and then taught regarding the worth of the souls of all men (10-13).
It has been said that a wise man will answer the question that should have been asked - not necessarily the one that is asked.  In this case, could it be that the Lord is responding to the question, "What do I need to know and do to prepare myself for this greater Melchizedek Priesthood?" instead of, "When will I receive it?" If so the answer is both profound and fitting.
In this revelation Oliver is told that the world is "ripening in iniquity" (6) and to declare repentance unto them (15-16).  He is also told that a whole life's effort dedicated to this cause - even if it only brought one soul to the Lord  - would bring great joy with that person in heaven.
In my experience there is likely nothing more important for a potential Melchizedek Priesthood holder to understand than the eternal worth of all souls to God, the infinite price paid for them through the Savior's atonement, and the great opportunity we have to seek and save them throughout our lives.
One word rivets my attention particularly in this section.  The word is "REMEMBER."  In verse 10 the Lord tells Oliver to "Remember, the worth of souls is great in the sight of God."  If Elders would consistently remember this - how valuable each of the Lord's children truly are to him - would it be possible for them to forget home teaching?  Would they neglect their family duties?  What a profound and perfect teacher the Lord is.
