The value of a person.
I started thinking that maybe God could have done it better if after we reached adulthood, we could get these old decrepit bodies in our twenties, then work backward to the physical health we had then. It would be SO much better if we could have the health we had in our twenties, and the wisdom we get in old age! But then God showed me why he did it this way: We start off as babies - and we're cute, and sweet, and lovable. We're not very "useful" at this point, in terms of "work" or "productivity". What we are is pure love... (and CRAZY amounts of energy!) and in the pure love of a child, you can see God. Children grow, and learn, until their late teens/ early 20's when they're considered "adults". Talk to any 20 year old, and they're convinced that they're going to go out and conquer the world. Talk to any 50 year old, and they'll say, (as I do), "I was SUCH an idiot when I was 20". ...
