The way I believe in God is essentially spiritual naturalism. But I subscribe to many religious ideas, such as progressive revelation of the Baha'i Faith, the inner light of Quakerism, soft cultural omnism, panendeism, among others, that denies supernatural superstitions and see that which is of awe in natural experiences. More than anything else I am part of the Earthseed movement, or simply, the idea that God is change and we must shape, or help create, God ourselves.
To explain it more fully, my umbrella camp is spiritual naturalism. Earthseed shapers are spiritual naturalists. Syntheists are Earthseed shapers. Exaltists are Syntheists. But all Exaltists are Syntheists, all Syntheists are Earthseed shapers, all Earthseed shapers are spiritual naturalists. Like a circle inside a circle inside another circle.
When I was growing up I had virtually no spirituality. I was pretty agnostic about the whole experience. And because I still reject supernaturalism, I view those who gaslight themselves over it to be correct in their assumptions. But, because I am of awe in nature, the fact that the Earth has existed for billions of years, not thousands, and in of awe of evolution, and the new ways we adapt to changes in our environment, lead me to have a deep spirituality that I was lacking as a child, but I developed as a teen, and now as an adult I'm more spiritual now and reaffirm that spirituality with nature rather than revealed religion or supernaturalism.
