I hated it when I got called on to give a prayer, such as for field circus. Jehovah did not answer any of my personal prayers because His purpose was to make my life as miserable as possible while still creating the illusion to others that I still had the obligation to serve Him, and thus I did not want His blessing to be upon the field circus.
I hated to ask Him to help us to reach the "lost sheep". You see, I actually wanted to see not at homes, doors slammed in our faces, and hours of wasted time trying to hunt for the place. If anything, my "silent prayers" were to Satan that he help confuse the driver so they will have to waste time backtracking or get extra errands or a flat tire, or that he give someone a Big Mac attack in the middle of the street so that the work would be cut short. I also prayed (silently) to Satan each time we were at a door, that the person not be home (and when someone did come, that they would be not interested).
And prayers at meetings, like the book study, were as bad. I had to pray that Jehovah would open the minds of people to take in those lies, and that the misery would be spread worldwide with people strengthened by opposition. What I really wanted was for a fire alarm to go off and cut the meeting short, for people to start thinking and give a comment like Blondie's Comments You Will Not Hear, or for the leaders to start educating instead of persecuting and that people would see zero or negative value in the "prize". More than anything, I wanted the meeting to be cut way short and for service to amount to nothing more than wasting an hour doing nothing and then going home.
