NAIROBI: The story Old Nyati was telling us was shocking. It was about an explosion in Kenya of a deeply disturbing phenomenon – thieving, lying and criminal pastors. He told us about one called Apostle Konyagi, who would con his congregants of thousands of shillings by convincing them he could heal their spiritual and physical ailments. He expelled demons from their bodies, extracted needles from their feet and cured them of HIV.
