This is all just an excuse for the method failing.
Either you have a method to test this god or you don't.
Blaming other people for not being genuine is absurd.

even eventually after time.
So how can you say the method has failed.
I guess it's like people for whom marriage doesn't work, they think others must be faking marital bliss or success.
