Mere Christianity PB by CS Lewis
In the classic Mere Christianity, C.S. Lewis, one of the most important writers of the 20th century, explores the common ground upon which all of those of Christian faith stand together.
The book brings together C. S. Lewis's legendary radio broadcasts during the war years, in which he set out simply to "explain and defend the belief that has been common to nearly all Christians at all times."
Rejecting the boundaries that divide Christianity's many denominations, Mere Christianity provides an unequalled opportunity for believers and nonbelievers alike to absorb a powerful, rational case for the Christian faith.
"C. S. Lewis understood, like few in the past century, just how deeply faith is both imaginative and rational."
