I once saw a tiny hornet make a 3000 pound bull jump a fence.
Small things can be very powerful.
I have on my desk a small acorn. I found it one day while out on a walk through the forest. I looked up to see all around me the mighty acorn trees that grew so tall and strong - all of them beginning with just such a tiny seed. I keep it on my desk to remind me that no matter how small my contribution, God can take it and make it something larger, something that will be a blessing to people. 31- 33 in Matthew 13 are about the power of small things.
