He turned into dust. He never turned into a tree. Not yet. Unless he decomposed so much that some errant seed turned into a sapling after his coffin decays. So we have a few centuries to wait on that one.
Yet another reason to be cremated and not buried in a coffin that takes decades to rot away. We understand. Our bodies are vessels. Our souls move on. Putting our bodies in a coffin just takes up room. How does that song go? What does it say in the bible? Ashes to ashes? Dust to dust? I know I'm going to the ocean as dolphin food. Amen!! :) :)
