In another life when I worked in restaurants I used to work with a fiery, belligerent Christian theology student.
When I would get a horrific tip I would punch it into the computer while saying something to the effect of; ‘I hope you die of facial cancer’ or ‘I hope you do not survive the one car accident I wish upon you’.
Said theology student asked me why I was saying such things.
My response was, ‘It makes me feel better, plus if I put that energy into the universe, it is possible it may happen’.
‘I don’t know why you’re just saying things to yourself that do not matter and will come to nothing, even if it makes you feel better.’
My same thoughts on his type of prayer.
