He Never Changes

He never changes, but I; well I am always changing. I'm so high, I'm so low. I'm so hot, I'm so cold. So young, so old. I'm at peace, I'm at war. I want less, but I want more. I want it all, but I'm not even sure what its for. I thank Him for loving me just the same, every day. His love never changes. When will ours?
