I read Joshua decades ago in my young adulthood, along with a few of the sequels.
I didn't agree with all of the sentiments expressed in the books, but then, of course, I didn't expect to.
What I found in the books was a fresh telling of a Jesus-like character ... who wasn't afraid to live among His people, sharing their highs and lows, their doubts and fears, their short-comings and their nobilities.
For a similar telling (of Jesus living among us on Earth), see "The Master Christian", written by Marie Corelli, published in 1900.
