God created it all. Every living thing. Everyday, there is so much going on in the natural simultaenously that we don't see with the naked eye or simply don't give our attention to. Bees creating honey and hives, worms making holes in the soil, birds building nests, waves crashing against the shore, the sun setting and rising and the moon waiting its turn. There is such order and a delicate balance, its simply miraculous.
But us humans in our weaknesses and limited knowledge doubt God's ability to keep His promises. He made the heavens and the earth. He made us. Can He truly not restore your family, marriage, health, finances or friendships? Of course He can! We just need to take a look around and marvel at His works and all He can do. He is everywhere. Have faith in Him.
