Think about the thought God put into all that He created. He created so much with our enjoyment in mind. He could have found a way for the leaves to fall to the ground in the Autumn without infusing them with color. He could have found a way for the birds and animals to attract a mate using something other than their melodious calls and vivid colors.
He is an artist. Our world is his canvas. He creates his masterpieces for our enjoyment as well as his own. Praise him for it!
