@thefr0g:
I'm sorry you feel that way.

@ Jordyn:

It's not really personal energy, nor is it personal desire. All power comes from God, and it's understood and made clear that in what they do, all glory goes to Him, not them. None of my friends use their abilities for anything really that selfish, either. I have one friend that reads tarot for people, another that's been doing rune castings for her friends, and another that, well, for example, offered and performed a spell for me to chase away some rather nasty recurring nightmares I've been having lately about my family and my fiancée.

Christian Mysticism in the traditional sense is more complex, and it involves a lot of things that I'm not very familiar with (there is a Wikipedia article that can tell more than I ever could). But the more modern usage, at least that I'm familiar with, could also be classified as New-Age Christianity, where psychic ability and the such is not accused of being straight from Hell, but rather a gift from God to be used to help others.
