Reality is NOT limited to our scientific understanding of nature. Events are not always the results of naturalistic processes. The early founders of science knew this. They recognized science for what it was, a tool to study the creation of God, not a tool to make the creation god. In the real reality, there are supernatural forces at work— just like the Bible says. They are usually very subtle and not apparent at all, but they are there. Again I think that dowsing is occultic and does NOT come from God, even though I have known Christians who practiced it (but I can’t help but wonder why).
