His rapidly growing religious movement and his teaching of prosperity theology have been a source of controversy. His sermons partly focus on freeing his followers from unclean spirits that oppress them, which manifest in them, and are cast out in the name of Jesus, for them to overcome their problems. His views about other faiths, particularly Catholicism, are also controversial. In 1992 he spent eleven days in jail on accusations of charlatanism. There were several protests, with his religious followers camping in front of the police precinct he was held in, according to his autobiography "Nothing to Lose". His prosperity theology is used by church leaders to justify his lifestyle, "If I preach prosperity and my clothes are ragged, who will follow me?"
