The Christian life depends upon faith, but there are good reasons for that faith. In Know Why You Believe professor and author K. Scott Oliphint answers the "why" questions both Christians and non-Christians often ask, laying out a simple and convincing case for the core teachings of Christianity.

As part of the KNOW series, Know Why You Believe is designed for personal study or classroom use, but also for small groups and Sunday schools wanting to better understand the traditional defenses of Christian belief. Each chapter covers a foundational teaching and includes a rationale for that teaching, responses to common objections, reflection questions to prompt further consideration, and suggested readings for readers wanting to dig deeper.

In this highly controversial book, Sam Harris seeks to link morality to the rest of human knowledge. Defining morality in terms of human and animal well-being, Harris argues that science can do more than tell how we are; it can, in principle, tell us how we ought to be. In his view, moral relativism is simply false--and comes at an increasing cost to humanity. And the intrusions of religion into the sphere of human values can be finally repelled: for just as there is no such thing as Christian physics or Muslim algebra, there can be no Christian or Muslim morality. Using his expertise in philosophy and neuroscience, along with his experience on the front lines of our "culture wars," Harris delivers a game-changing book about the future of science and about the real basis of human cooperation.

In The New Flatlanders, teacher, scientist, and chaplain Eric Middleton challenges traditional ways of looking at reality by engaging readers in a "voyage of discovery starting with questions." The book engagingly begins with a discussion group embarking on an exploratory conversation about the nature of the universe and the place of human beings in it. Daunting questions emerge, such as "How can there possibly be a tear or hole in three-dimensional space? And if there is a hole, can something fall through it? Where would it fall to?" In short order, students and teacher are on a quest to develop a "working theory of everything" that takes them from stone circles to quarks, superstrings, quantum theory, the anthropic principle, evolution, consciousness, miracles, chaos, and the spiritual universe.

The key to exploring these questions is finding a language with which to talk about the awe and wonder of today's science alongside the joy of experiencing the spiritual. This is done by interweaving into the discussions the philosophy of "Flatland," a nonreligious entry point to Jesus posited by nineteenth-century clergyman and educator Edwin A. Abbott in his classic parable Flatland: A Romance of Many Dimensions.
