He's not the only one who does that kind of stuff. Jesus did that all the time a while ago. One of the things he said is: everything I do, you can do it too.
Even today he's not the only one who does that kind of things, although I don't think there are more than a dozen people in the world who are as effective. I personally know many healers.
Carolyne Miss did heal AIDS and wrote a book about it: AIDS: Passageway to Transformation

Miraculous healing happens every now and then in hospitals. They talk about a few cases in the movie The Secret, including a case of cancer.
Besides seeing him bring massive changes to my life and to the life of a bunch of other people in a very very short period of time, I've seen him remove child-birth marks on women' stomach. There was a man who is blind since birth. He got him to see a little bit his hand but he wasn't ready to have vision so he didn't go further. My mom also just healed from a small breast cancer. She's very religious but she doesn't believe in healing. In her case she had a hospital intervention and was just VERY lucky after I asked Jacques to simply do a prayer for her.
I think the high-level stuff he does is irrelevant for us. What matters is many of the basic concepts he teaches about the fundamentals of our energetic systems.
He wrote a book which I have but I still haven't read it. Warning: it's very advanced stuff. He also has a set of meditation CDs. Warning: that's 1 year worth of meditation! (if you have the patience!)
