This book builds a ground-level-up argument for not just the existence for God, but for why Christianity is the only religion that adequately makes sense of the universe as we know it. It begins with an exploration of human nature, which is followed by an explanation of what Christians believe, it's morality, and finally a section on the trinity. Although the last section of the book is, biblically, theologically sketchy, it\\r\\nis a great book to give to those who are seriously questioning Christianity, or for Christians who wish to understand God (and themselves) better, and is understandably considered one of the most influential books in Christian literature in the modern era.
