Someone --- I think it was Spencer W Kimball --- said remember is the most important word in the dictionary. Personally, I think any statement like that is inherently silly, but the concept of remembering is certainly important. Helaman certainly thought so.
I had this idea when I was younger that sometimes old acquaintances will bring up and ask me if I still believe this (answer: I don't know) that we're born knowing everything and life is but a process of remembering what we have forgotten. I don't know how true this is generally, but with pure spiritual concepts, I still accept it as true. We know we are loved, for instance, and at times, we remember.
Let's keep remembering.
