D&C 42

 The Lord instructed - 

 "If thou shalt ask, thou shalt receive revelation upon revelation, knowledge upon knowledge, that thou mayest know the mysteries and peaceable things—that which bringeth joy, that which bringeth life eternal.

62 Thou shalt ask, and it shall be revealed unto you in mine own due time where the New Jerusalem shall be built."  (Doctrine and Covenants 42:61–62)

My thoughts this morning seem to be concerning His temples.  Over the years, His temples were used for varying purposes, ie sacrifices.  Today, temples are primarily used for knowledge, mercy, ordinances, covenants, and sealing.  But the temple in the New Jerusalem may be for priesthood administration for the work of the millennium.  Who knows.
