The Lord Can “Enlighten” Our Minds

Doctrine and Covenants 6:14–15

14 Verily, verily, I say unto thee, 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.

President Harold B. Lee said:

“The Lord, by revelation, brings [ideas] into our mind as though a voice were speaking. May I bear humble testimony, if I may be pardoned, to that fact? I was once in a situation where I needed help. The Lord knew I needed help and I was on an important mission. I was awakened in the hours of the morning as though someone had wakened me to straighten me out on something that I had planned to do in a contrary course, and there was clearly mapped out before me as I lay there that morning, just as surely as though someone had sat on the edge of my bed and told me what to do. Yes, the voice of the Lord comes into our minds and we are directed thereby.”
