It received rave reviews from S. Lewis and Philip Yancey.

While reading this book, I felt like I was driving a car at over 200 kilometers per hour.
I would get up in the middle of the road, walk around, catch my breath, then sit back down to read and admire, then get up again to rest, then pick up the book and read again. This process repeated countless times.
“It’s Chesterton!” Those were the last words I could say.

When someone asked Chesterton what book he would take with him if he were stranded on a desert island, he thought for a moment and then replied, “A practical guide to shipbuilding, of course.”

Becoming a Christian allows you to experience the following joys:
It is the joy of recognizing clearly that one is not alone with one's inner light, and that there is a light outside, as beautiful as the sun, as clear as the moon, and as fearsome as a disciplined army.
--- p.175~176

The foreign thought was like a marble pillar standing upright, symmetrically balanced.
Christianity was like a gigantic, rugged, romantic rock that swayed when its pedestal was disturbed, yet its derivatives balanced each other out, so that it remained on the throne for a thousand years.

If you want the pillar to stay white, you'll have to repaint it.
So to speak, you always have to make a revolution.

Depression should be a temporary state of mind that occurs between verses, like an interlude.
Praise, on the other hand, must become the permanent pulse of the soul.
Pessimism is at best an emotional half-holiday.
Joy is like the noisy labor that makes everything alive and breathing.
