I really enjoyed Mark Twain: A Christian Response to His Battle With God by Ray Comfort. It was a revealing look at a guy who is often cited by atheists as one of their own.
I actually read the book (unlike some reviewers – apparently one guy gave it and 93 other Christian books 1 star). It was fascinating to see how Twain’s thinking radically changed when bad things happened to him. Like many people, all the world’s tragedies were no big deal until something bad happened to them. Then it was God’s fault — no, they say He doesn’t exist — but they are mad at him anyway!
I hope a lot of people read this book. Twain was obviously not a Christian, but he was anything but an atheist. Oddly, he never blamed who he saw as the “real” god for everything that happened in the world.
A commentator of Clemens noted: As the years went by and he became successful, he became relatively conciliatory toward religion, but as his fortunes reversed late in life, he became bitterly sarcastic and hostile.
