Why do I take the sacrament?
To remember, but just what exactly it is that I'm trying to recall is something I often struggle with. And then I'm reminded and I start all over again... Do I need to remember my abstract formulations of who Jesus was and the mechanics of how the Atonement works insofar as I understand them? That's certainly part of it, but the knowledge needs to go deeper than that. There are other neural pathways (and spiritual ones) that need to be accessed. It is said "by the power of the Holy Ghost ye may know the truth of all things" and that "Angels speak by the power of the Holy Ghost; wherefore, they speak the words of Christ. Wherefore, I said unto you, feast upon the words of Christ; for behold, the words of Christ will tell you all things what ye should do." So, to entertain the truth of what I'm remembering on a purely intellectual level would leave my knowledge of the reality of the divinity of Christ on par with the rest of my memorized facts about the world. However, these scriptures offer a valuable insight: stating that there is a special (non-provisional) knowledge available through a witness given by the Holy Ghost. The question is have I experienced this? Yes. OK, back to the beginning again, that's why I take the sacrament to remember the Atonement based on my own actual spiritual experience of its reality.
