Is it possible that prayer is just a way to manifest our desires?
Almost everyone knows how the law of attraction works...
You think about shit and said shit happens.
I've heard of a lot of people praying, over and over for something. I remember my cello teacher told me that when she was younger she and her mother prayed hard for a cello, and someone sold them a very expensive one for a cheap price.
If God exists, he's probably a busy guy. Maybe he gave everyone an equal chance to grant their own desires.
Or maybe he doesn't exist and almost every single answered prayer is the result of manifestation.
Anyway, it was just a thought.
