No, no, no.. I was suggesting it for your view - if you can have "conclusive proof" about yourself, then someone else could get it about you by asking you.
Unless you lie of course. :)
Oh, OK, that's very different. ......... Nevermind. :) However, that wouldn't work for us either because there are some false believers. There are those who will claim "Lord, Lord", etc. So, it can't constitute proof.
