God is Sovereign. He can use anything, anybody, anyone to accomplish His will on Earth as well as in Heaven. Elijah had to trust God with no questions asked, Elijah dependency on God is evidence as he waits to be fed both morning and evening. (It's not like waiting on Grub Hub with an order of food that you know will get delivered).
God will make it alright for us, He will make perfect everything concerning us while we wait for His provision.
