The Mormons . do not believe in the power of the spirit of god. or do they?

.They called my crazy for telling them of some miracles that had happened in my family, is this reason to say there not a godly group of people.They said that only priests and other people in there church can preform miracles.? I do not think anyone can, it is thru the spirit of god , that is where miracles, happen, I had gone to there church three times, they visited many times, I gave them gifts and money, but when I mentioned miracles, they got up and called me crazy and left, whats with those people. I am glad I didnt get babtised into that church.has anyone else had experiances like I had.in jacksonville florida,recently?or anywhere. is this a common practice.to denie the spirit of gods miracles. to denie the spirit is the only unpardonable sin.
