Sometimes I get random words or phrases stuck in my head, and the other night it happened to be, "How knoweth a man..." I couldn't remember the rest, but I knew it was a scripture. Then yesterday I remembered that it says, "How knoweth a man the master whom he has not served?"
Today I looked up the scripture, which is Mosiah 5: 13:
For how knoweth a man the master whom he has not served, and who is a stranger unto him, and is far from the thoughts and intents of his heart?
I was sitting there pondering what in my life had caused this scripture to bubble into my consciousness, when I read the previous verse, verse 12:
I say unto you, I would that ye should remember to retain the name written always in your hearts, that ye are not found on the left hand of God, but that ye hear and know the voice by which ye shall be called, and also, the name by which he shall call you.
That verse reminded me of a moment I had in the MTC, which I am about to relate to you.
I was in one of the large group meetings, and was, well, falling asleep. Yes, I sometimes fell asleep in the MTC when I wasn't supposed to. I think this is normal if you're used to going to bed at 2am and then suddenly try to switch to 10:30pm. But that is beside the point. I was falling asleep, when my district leader (who was sitting a few rows behind me) took the microphone to make a comment.
When I heard Elder S.'s voice, I immediately sat up and became alert. I wondered why his voice had such an impact on me, then realized that it was because I knew his voice, and I knew him, and I wanted to know what he had to say.
This is why I need to be familiar with the Savior and His voice. For me, I can't say that I've ever heard the Savior literally speak from His own mouth, but I have heard Him speak through prophets, through the scriptures, through other people, and through the promptings of the Holy Ghost.
If I'm familiar with His voice, and know Him, and want to hear what He has to say, I'm going to be more likely to wake up and listen when He speaks. I could also try going to bed earlier, but I don't think that'd work quite as well. :o)
