This truth can be corroborated by countless phenomena in the visible world [around us], for the universe is like a stage on which proofs are constantly being demonstrated that God exists and that there is one God.
By way of illustration I will cite a memorable occurrence that I experienced in the spiritual world: Once when I was having a conversation with angels, there were several people present who had recently arrived from the physical world. When I saw them I wished them a happy arrival and told them a number of things they would not otherwise have known about the spiritual world. After that I asked them what considered opinions about God and nature they were bringing with them from the world.
Their answer was this: “Nature produces everything that occurs in the created universe. After creation, God endowed nature with this productive power and ability; he imprinted this power on it. God’s only role [now] is to maintain nature’s productive power and ability and keep them from failing. Therefore these days everything in the world that comes about and is produced or reproduced is attributed to nature.”
I replied that nature of itself does nothing; it is God who produces things through nature. They asked me to prove it. So I said, “People who believe that the Divine is at work in every detail of nature find support for a belief in God in many of the phenomena they observe in the world. They find much more evidence to support a belief in God than to support a belief in nature.
