Brilliant. As much as I loved his The Reason for God, I feel this presentation is even better. Keller shows that theism is a rational position...more rational than naturalism, materialism, secularism, humanism and more. He gives a rational defence of the Christian faith in particular, going beyond mere theism to present many ways to approach worldviews that reveal a compelling case for Christianity. As a committed believer myself, I am biased in favour of what he writes here, but I am nonetheless impressed by the lucidity of his work, the depth of scholarship and more. His endnotes went far beyond referencing the sources he used and included more commentary that was, in and of itself, all by itself, worth the price of the book. I look forward to reading the next 2 of his books that I have ordered.

And, indeed, this "invitation to the skeptical" merits a careful perusal by any skeptic of Christian faith. ( )

In some ways, it is not fair for me to review this book. I am not the clearly stated target audience. So I can't say for sure it would be effective. I will say I thought the last part of the book seemed better than the first sections. If you are in the target audience, I think this might be good. ( )

Quote (Timothy Keller): "Believers and nonbelievers in God alike arrive at their positions through a combination of experience, faith, reasoning, and intuition."
Quote (Timothy Keller): "Neither religion nor secularity can be demonstrably proven -- they are systems of thinking and believing that need to be compared and contrasted to one another in order to determine which makes the most sense." ( )
