For that, too, is in the natural order. The Kingdom of Heaven is within us. The Universe is perfect as it is. At any time we can recognize the perfection of this miracle we call life. Yet, at the same time, we should realize that evolution, both physical and spiritual, is the very nature of life, and is an essential part of life.
Evolution is the purpose that explains all the seeming imperfections.
Though Heaven is not a time or place, God has given us everything we need to create a paradise here on this Earth. We should expect the very best from ourselves, and from humanity, for God has given us the best of teachers, the best of tools, and the best of worlds. And best of all, free will, that we might co-create a heaven here ourselves. It is happening. Many people and many books have spoken of a Golden Age to come.
