I am not suggesting that there are ways for you to generate new physical body parts in the privacy of your home. Rather, it is my hope that I can convince you to approach religion and faith from a more visceral and organic perspective.
Basically, religion promises eternal life and happiness in a spiritual realm that exists beyond time and space and beyond our ocular detection. Thankfully, the spiritual world and heaven can indeed be brought into the field of vision of our understanding and rational powers.
For instance, we know from direct observation that all living things have adapted and evolved their bodies to take advantage of some niche in nature. Fish have fins, birds have wings and humans have big brains. The human race has procured for itself a most unique niche in the universe. Humans not only gather food for their bodies but information to feed their minds.
Religion addresses this human trajectory in evolution by providing special information (doctrine and God’s tenets) so that we can evolve our hearts and minds to adapt to a blessed life in a heavenly paradise and biosphere. So even if we believe we have an eternal soul, religion teaches that something extra is needed to transfer our personhood (subjective experience) from the physical world to the spiritual world.
This vehicle for transporting our life and personality into a non-physical realm is called a “spiritual body.” According to scientist/theologian Emanuel Swedenborg, the soul is even beyond the consciousness of angels. The soul, however, forms for us a spiritual body according to the choices we make in life and our particular worldview. Otherwise, our personal life and experience could not continue into heaven.
What is not taken into account in the world is that the choices we make and the beliefs we cultivate are the vital organs that make up our spiritual bodies. The reason for this is that these are the things that provide the life-giving functions to our spirits and metabolize our information! (That our thoughts and feelings have a human form is evidenced by the fact that the mind is correlated to the brain and the brain is correlated with everything in the physical body—one corresponds to the other.) This generative process of growing spiritual body parts is what is meant by the Lord’s decree that we must be “reborn.”
True religion is God’s wise strategy for continuing the trajectory of evolution into the heavenly kingdom. Knowing about the need to create a spiritual body that is specially adapted to exploit (enjoy) the heavenly niche of mutual love takes religion and faith out of the realm of mere devotion and into the light of logic and intellectual credibility.
I expand on this theme in my new book Proving God.
