I've been keeping track of my prayers this month and periodically I check the list. So far, it is as follows:
Yes (as in clear, no question YES)--8
No (as in clear, no question NO)--0
Unclear if it was yes or no, muddy answer--3
The yeses have often been rather small things, like getting a project done quickly.
The unclear have generally leaned toward "no" rather than "yes."
The no answer tend to be on more major things like resolution of a law suit, medical tests, and finances.
So there it is.
