What informs your guess on his illiteracy? Or is it a wild guess
He might well have been literate. He argues scriptures with other rabbis. Will I be caught arguing that these were rational folks? Far from it. TB Josh lives in harsh times.
He was a carpenter. I just assumed a carpenter in the first century was illiterate.
I cannot argue that TB Josh has it easier or even as easy as a preacher in the first century.
When I think of what TB Josh could do with a first century audience, I cannot easily suppress laughter.
Now give him 2,000 years lag time and I wont go there. I value my ribs.
