Memory

I'm memorizing Psalm 103 right now...feel free to join me.

How did God decide to create the memory? If the world wasn't fallen, would our memories be perfect? Are some people better images of God because they can remember more and remember more clearly? Are photographic memories what we're all supposed to have?

What made God so solidly connect smell to memory? What hidden mystery is there here?

The idea of our prayers and offerings and lives in general being pleasing aroma's to the Lord...does this have any significance here?
