I personally agree with Angel and Ash. It works for me. I've seen it, I've used it, it's helped me. An example is this last year, when my wife and I were going to buy a house. We found one we really liked, but it was a little more than we wanted to spend - but we kept being drawn to the house. So, we prayed about it, and asked for guidance and God to confirm that it was the right house. After the prayer, I had the Bible and half-jokingly said I was going to open the Bible to a random page and point at a random place and look for an answer. I opened it, pointed and landed on the words "God's confirmation." That worked for us.
Now, I'm sure a lot of you will write that off as coincidence - but by the sheer number of verses, books, and chapters in the bible - landing on one that had the verbatim words I was looking for was more than that for me. And ironically, the ones who write it off as coincidence will be the same ones talking about karma in another thread someday.
