My faith does not come from watching a video or even hearing someone else's testimony. It has to do with my own walk, my own life, and my own faith.
What many fake faith healers do is justify faking a miracle in order to build faith as though that is how it's done. Yes, it temporarily does build one's faith but it's not a lasting faith. It's not the type that weathers the storms of life. You can't manufacturer true faith.
