One Question

Hello everyone.

I am no longer a Christian anymore. I recently made the decision, and simultaneously discovered this great site. I found that I could no longer believe in the stories of the Bible, lacking any concrete evidence. I also could not accept some of the terrible morality that the Bible espouses. I am much happier now, but I had a question to ask that has kind of been bothering me for a while.

How can the supposed healings in Christian churches be explained? I realize in most cases, people are not healed. I was sick for over a year and tried to be healed multiple times, but it never happened. My aunt has cancer has has been healed multiple times, but she is still sick. But, it seems that some people are healed. How can we explain this? And I've heard about personal accounts of people seeing miracles and what not? Is the only explanation that these people are delusional or lying?
