So, I was thinking about the atoms in the universe. They get recycled constantly. The oxygen molecule I breathe in probably was transformed by a plant from carbon dioxide, which might have been released by a bacteria that ate a molecule of some nasty pollutant, which stole the oxygen from the water column in a stream, which incorporated it from the atmosphere, which.... Well, you get the idea. I read once that every atom in our bodies is exchanged over a 3-year period. I really am a different person than I was 3 years ago!
There is some mysterious way in which we are so linked to all of creation that our attitudes toward God affect the natural world. Obedience to God will allow the trees to "clap their hands," and the hills to "skip for joy." (Isaiah 35:1-8 has an example of the response of the natural world to holiness) But when we sin, rebel, act deceitfully, or worship other gods, all creation responds with lowered production, or lowered resistance to pollution. (Jeremiah 7:17-20 is one example) Creation also suffers in our judgment.
The physical, atomic, material parts of us are real. God's creation of them granted them a reality. But as noted above this material universe is totally fluid. Is my big toe made up of an atom of the star Betelgeuse, one of elm bark, and another of leopard spots? More to the point, is the Mississippi River made up of atoms of me, Jesse James, Billy Graham, the Unibomber, and of you? Do these recycled atoms somehow mystically carry the imprint of my spirit?
Can I literally make the world a holy, or a godless place just by the nature of the atomic fairy dust I sprinkle everywhere?
