These are the mantras that reverberate across Africa in the world of faith healing. The practice was thrust into the spotlight again through the tragic incident in Nigeria recently, when more than 100 people were killed. They had traveled to seek guidance and healing from a Christian televangelist, self-proclaimed ＂prophet＂ T.B. Joshua, and died when the building they were staying in （which was owned by Joshua） collapsed.展开更多
