Permission to Receive
Though believing in Torah Min Hashamayim requires one to first believe in Hashem.
I read some of the reviews on Amazon to get the gist of it.
From what I read there, I think the strongest argument (which IMHO talks also on levels other than intellect) is:
In the first case, he wonders why secular Bible critics have ignored the mass of commentary in the Talmud expressly devoted to explaining all the apparent textual contradictions that secular critics seem to think nobody ever noticed before.
This can be rephrased with a little more context, bringing to the surface the breadth of knowledge and understanding of true gedolei Yisroel, starting with תנאים ואמוראים, and continuing throughput the generations. All of those were definitely familiar with any questions you might have, and had a much wider knowledge, allowing them to see even questions you don't see, yet they are steadfast in יג עיקרים!
I think that once one internalizes this reality, all counter arguments (as seen in negative review) become irrelevant.
