D&C 6

The Lord provides some great incite as He tells Oliver Cowdery -

"...blessed art thou for what thou hast done; for thou hast inquired of me, and behold, as often as thou hast inquired thou hast received instruction of my Spirit.  If it had not been so, thou wouldst not have come to the place where thou art at this time.
15 Behold, thou knowest that thou hast inquired of me and I did enlighten thy mind; and now I tell thee these things that thou mayest know that thou hast been enlightened by the Spirit of truth..."  (Doctrine and Covenants | Section 6:14 - 15)

What I find interesting is the Lord is teaching us that many times, as we look back at our experiences, we recognize not only the hand of the Lord in our lives, but we recognize the influence of the Holy Ghost and the promptings and feelings we received.

Thus we are always counseled -

"...O remember, remember..."  (Book of Mormon | Mosiah 2:41)
