Do Christians literally believe that Jesus could do magic?

Believe me, I used to be a sceptic until I worked in a haunted pub 13 years ago, I've seen and heard weird things, this ghost could even open windows, shut doors, set of the indoor security alarm, set off the mens and ladies handriers by themselves in the toilets and small children could see and hear the ghost talking, but adults heard no conversations, only occasional moans. When you can see items moving on their own in a building when you are all alone, then anything is possible. I strongly believe in good and evil, so the scriptures though sounds out of context to some, to me will be gospel.
