If real telekinesis was demonstrated, for example, that might qualify. I can be open to the possibility in the same way that I am open to any idea or theory that can be demonstrated successfully. I remain skeptical, however, until the thing under consideration can answer my questions about it. Such an attitude is exemplary, indeed. This is something with which I can strongly agree.
Spirituality is independent of any religious preference.
I haven't read that particular book, but I have problems with the idea of how an all-benevolent Creator could allow his creations to suffer. Seems more like a self-fulfilling prophecy on the part of those doing the counting. Personally, I'd be far more impressed by the miraculous diversion or disappearance of a potentially killer tornado or hurricane than by the testimony of those who might survive it. What I have is a standard by which I judge all ideas and opinions. That standard does not change no matter the source of the thing in question.
