Here is a picture I stumbled upon online last November. The caption alleged it was a picture of Archbishop Benson Idahosa imparting Evangelist Reinhard Bonnke. If that is factual and I believe it is, then this event took place 1986 in Zimbabwe on a conference for evangelists organised by Reinhard Bonnke.
This year made it 20 years since Benson Idahosa went to glory and I kind of believe he is an unsung hero in some ways. He was a mighty force for God all over the world
