Memory

Today I heard a song that I used to listen to in junior high or high school.  Today was the first time since then that I've listened to it.  But, amazingly enough, I could remember every word.  Isn't it interesting how our brains work?  I haven't even thought of that song for years, but I remembered it all; it was still in my head, and I knew it when I heard it.  I wonder if the same patterns of memory and recall apply to our spiritual lives.  I don't remember what my pre-mortal existence was like.  I don't remember what Heavenly Father's face looks like.  But I think that knowledge is still in me or a part of me somewhere.  Maybe that's why when the Holy Ghost testifies of a spiritual truth, it resonates with us; because we already know it.
