Considering the locusts

Luke 12:24 "Consider the ravens: they do not sow or reap, they have no storeroom or barn; yet God feeds them. And how much more valuable you are than the birds!"

My 6 year old and 3 year old are non-stop question askers. Anything they see that they don't know what it is they inquire about. Animals and bugs are a common subjects of their inquiries. "Why does a dog _____?" "How does a cow know to _______?" "What does a _______ eat?" More questions than I can possibly answer or KNOW the answer to. Thankfully, I believe that ultimately God knows why His creations act they way they do, so my "go to" answer is usually "that's just how God made them." I've often wondered how athiests answer their kids questions about nature/animal type things.
Lately there have been more questions about locusts than any other bug. We have a lot of them in our country yard - every day there are new cicada shells. We've even seen a few coming out of their shell. They are incredibly slow, so we have not watched one hatch from start to finish, but the kids get the picture of what happens to them. Just 2 days ago the kids saw a cicada crawling pretty fast across the yard and they beconed me to come out and watch. I am a city girl at heart and so many of my kid's firsts when it comes to bugs is also a first for me, so I was happy to watch the bug as it went on it's adventure in the grass. One thing I've learned about locusts since moving to the country is that they have to be vertical in order to come out of their shell, so as I watched this bug in the grass I could see it was heading straight for a large tree next to our deck. "Mommy, how does it know to go to the tree?" "God told it to go there." "Mommy, when will it stop crawling?" "When God tells it to" "OOH, Mommy, why is it climbing so high?" "God is telling it to go there." You get the picture - the kids and I sat in the grass watching that cicada for probably 10 minutes or more.
All this bug observation has caused me to do some thinking. I totally believe that God has a plan for ALL of His creations and he knows all of his creations. From the little bitty locust, to the hugemongous whale and every creature in between - God cares for them. So, I think, If God cares for all of the animals how much MORE does he care for me, the creature he crafted in HIS image? Whenever I worry about what we would do if our van broke down, or how we would handle a major health crisis I need to remember Luke 24:12 and think about how valuable I am to God. Surely the locusts don't worry about where they will stop and come out of their shells - they don't sit in the ground waiting to come out and think about how hard it's going to be to get out of the ground. They know (sort of) that God takes care of all those things. So, in order to really bloom, I need to take into account how LOVED I am by the Creator of all Creatures and not worry about tomorrow for tomorrow will worry about itself - and tomorrow God will still be there to take my worries to.
