I first ran across this book ten years ago and have found myself continually buying copies for friends. Having just purchased it and reread it, yet again, I am convinced that, of Kreeft's many works, and among Christian apologetics generally, this one continues to stand out as foundational. By starting with the very "fundamentals lf the faith" in the first part of the book, Kreeft enables those with little or no understanding of Christianity to embrace it. He moves on to some of the tougher issues of the faith, and without flinching, presents a defense that is both philosophically and theologically sound. Finally, he turns to a series of essays on the Lord's Prayer that has continued to revitalize my prayer life. Overall, what makes this book such a winner for me is his clear, articulate prose -- and the fact that the book is presented in short essays that are ideal for an evening's consumption... if, in fact, you can resist the temptation to plough through the whole thing in a sitting.
