On the eve of his 95th birthday, Nelson Mandela's daughter conducted an interview in the home of former South African president's second wife Winnie, Zindzi Mandela. She was showing the reporter many gifts and memorabilia that were kept in the house.

Surprisingly, amongst the pictures which they considered to be exclusive there was a portrait of T.B. Joshua. That was something I didn't expect to see. What does this mean? Are Mandela and his family really Christian?
