This is a very interesting de-conversion story of Daniel Everett as he tried to evangelize to an indigenous (atheist) Amazonian Tribe. And in his attempt to convert them, he himself converted to a non-believer.
*He also has a book about this journey called Don’t Sleep there are Snakes.
I think the part that stood out to me in his story, is when the Pirahas people asked him; “Is this Jesus tall or Short?” Is this Jesus dark-skin or fair-skin like you?” and he had to admit to them that all this time he had been telling them about this man named Jesus that he did not actually know and never actually met. And that he was just repeating a story someone told him about Jesus.
Daniel struggled in trying to witness to the Pirahas people because when they would ask him practical questions about his abstract faith, God and Jesus, he could not give not a practical answer back.
