Still on the topic of talking with dead people, Jesus once encountered Moses and Elijah, two dead prophets, in a bright cloud of glory. He had an extensive conversation with them.
The dead continue to exist in some form. I'm not interested to communicate with the departed. I assume they're done with this life. And yet, they continue to exist in some way.
What I'm interested in, is how we try to wrap our minds around metaphysical, supernatural occurrences. Do we try to ignore the unexplainable? Do we try to explain it all away? Or are we able to sit with mystery, and allow our understanding of the unexplainable to grow effortlessly?
