Welcome For what it's worth (I'll get this out of the way right now), I'm not a Christian, but a Pagan. A good portion of the people on these forums think that I'm going to Hell (which I don't believe in the existance of), so be aware that from the Christian perspective my opinion in these matters may not be worth a whole lot
That being said, I believe that whatever you believe in that makes you a better person works. Is it right? Who knows? But if it keeps you going through your day and makes you feel as though you're doing something worthwhile I would say go for it.
In Paganism, the only Evil is in intent - if you use your Psionics to benfit people I don't really see a problem with it. Can you merge Christianity and Energy Manipulation (Psionics, Spellcraft, Magic)? That's between you and your Faith, IMO. I'm sure someone here can quote some stuff out of the Bible that either supports or denies my opinion, and I'd actually like to see some of it myself
Once again, consider the source. I'm not here to make trouble and I'm certainly not here to give "bad" information
