Divine Healing?

So, I'm reading two different books about God working through people to heal other people, or the gift of healing. And, honestly I'm not sure what I think about that--Oh, I've always believed that God does and can heal--and that He heals who He wills for whatever reason He chooses. But, to say that there's people out there that God works through to open the eyes of blind, to unstop deaf ears, to make maimed limbs straight, that's a bit of a leap for me. But, that's just what these people testify that God is and has done through them, or others they've known.

And, unlike other accounts I've read before all glory seems to be given to God, and not to the one being used. Sounds a whole lot like what I read about in the New Testament--Jesus healing the blind, Peter causing the lame to leap, Paul casting out devils and more. So, is it possible? Is it true?

And, I guess most importantly could God use me in this way? (Whether He chooses to or not is something altogether different, but could He use me in this way?)
