I would watch this latest episode of Sid Roth's "It's Supernatural!" Sid interviews Tommy Welchel, the last living witness of the Azusa Street Revival because one of the main things he shares is how God healed amputees and people who were missing limbs. You need to check it out.
Not to demean your credibility or anything, but have you noticed how these things never ever happen when there are high definition cameras and plenty of medical evidence around?
There is a reason for that.
