In my own young mind, it seemed to me that it was just a matter of faith. If it was desired enough, it could happen. From Kerygma, our own Bible study class, I also learned that the healings were meant to show how faith in God was synonymous with wholeness. As people's bodies were cured, their faith was kindled, and they were therefore made whole in body, mind and spirit. As someone born with a disability, I've thought about these ideas.
Some people think so.
A few years ago, I was sitting in the park near my home, minding my daughter, Katie, while she played. A woman approached me, wanting to know what I was doing there. She asked me if she could pray for me. So I decided to stall a bit. I asked her WHY she felt she needed to pray for me.
