Just reviewing my prayers and realising I had been talking to myself.
I was told that God only answers prayers in line with his will so you can't ask to win the lotto for instance.
I was very careful not to ask for "selfish" things but still nothing.
Then you have ones tell you that God helped them find their keys or something equally trivial that most people can do without any divine intervention.
I watched Serena Williams thank her God Jehovah when she won tennis but not help ones who really needed it.
Only logical conclusion is that he is not there.
