I do believe that miracles can happen - otherwise how can I
believe in God?
I do believe that healing had taken place before - otherwise how
can I believe in the Bible?
Having said all that.... it should also be noted that there are
many charlatans around. If there is a claim that healing had taken
place, there must also be a record that in the first place, healing
was necessary.
I can now pray for someone for healing for his headache, this chap
may recover immediately or within a period of time - did healing
took place or did the body reacted to some internal
mechanism?
The real issue is not such psychosomatic illness, but real cases,
eg documented cancer cases, or really lame folks (not some who'd
sprained his ankle) now standing up to walk, or, as I'd said, the
blind now seeing.
For a "miracle" service to be really credible, there must be some
kind of audit and credible independent testimony.
Ghosts? I am not into the supernatural, I don't think about it or
pay attention to it. When I travel and sleep in strange hotel
rooms, I turned off all the lights (because that's the way I like
it)..... yet, I have seen stuff (a couple of times) that appeared
close to me that I cannot explain.
