Everybody has one. It's called a "haunt detector". It's the little alarm that goes off in our heads whenever we detect that something mysterious or supernatural has occurred. You could be sitting around relaxing, and for no special reason you start thinking about someone. Then the phone rings; you pick it up, and amazingly, it's that person! Many of us have experienced this phenomenon.What is it? Anthony DeStefano answers this compelling question in his fascinating new book, The Invisible World.

Anthony DeStefano, the best-selling author of A Travel Guide to Heaven, takes us on an exploration of hell, the devil, demons, and evil itself.

Reasonable, concise, witty, and wise, Peter Kreeft and Ronald K. Tacelli have written an informative and valuable guidebook for anyone looking for answers to questions of faith and reason. Topics include: faith and reason, the existence of God, God's nature, how we know God, creation and evolution, providence and free will, miracles, and more.

Critics outside the church often accuse the Old Testament God of genocide, racism, ethnic cleansing, and violence. But a rising tide of critics within the church claim that Moses and other "primitive," violence-prone prophets were mistaken about God's commands and character. Both sets of critics dismiss this allegedly harsh, flawed, "textual" Old Testament God in favor of the kind, compassionate, "actual" God revealed by Jesus. Are they right to do so?

Few subjects are as compelling-or as endlessly variable-as love and marriage. The Bible is filled with references to husbands and wives, from the story of Adam and Eve to advice in the New Testament, each open to interpretation. In The Meaning of Marriage, Timothy Keller, pastor of New York's Redeemer Presbyterian Church and bestselling author of The Reason for God, uses the scriptures as his guide to show readers what God's call to marriage is, and why this is such a powerful call.

The path of following Jesus is an ancient and storied spiritual tradition. Yet many believers are not familiar with the three major forms of prayer and the three stages of spiritual growth that exist to bring them closer to God. In his most personal book yet, Brant Pitre, PhD, draws on the riches of the Bible, the words of Jesus, and the writings of mystics across the centuries to shed light on the mystery - and wonder - of the spiritual life.

Seeking to reopen the debate, Justin Brierley began to invite atheists and sceptics on to Premier Christian Radio to air arguments for and against the Christian faith.

Drawing upon the teachings of seven spiritual doctors of the church, Ralph Martin presents an in-depth study of the journey to God. This book provides encouragement and direction for the pilgrim who desires to know, love, and serve our Lord.

Militant atheism is on the rise. In recent years, Richard Dawkins, Sam Harris, Daniel Dennett, and Christopher Hitchens have produced a steady stream of best-selling books denigrating religious belief. These authors are merely the leading edge of a larger movement that includes much of the scientific community. In response, mathematician David Berlinski, himself a secular Jew, delivers a biting defense of religious thought.

Discover magazine recently called Richard Dawkins "Darwin's Rottweiler" for his fierce and effective defense of evolution. Prospect magazine voted him among the top three public intellectuals in the world (along with Umberto Eco and Noam Chomsky). Now Dawkins turns his considerable intellect on religion, denouncing its faulty logic and the suffering it causes.

"Forty-four percent of the American population is convinced that Jesus will return to judge the living and the dead sometime in the next 50 years," writes Sam Harris. "Imagine the consequences if any significant component of the U.S. government actually believed that the world was about to end and that its ending would be glorious. The fact that nearly half of the American population apparently believes this...should be considered a moral and intellectual emergency."

Is Christianity obsolete? Can an intelligent, educated person really believe the Bible? Or do the atheists have it right? In his new book, best-selling author Dinesh D'Souza ( What's So Great about America) investigates both Christianity and atheism and their influences on culture to show why there is, indeed, something great about Christianity.

Mere Christianity is C.S. Lewis' forceful and accessible doctrine of Christian belief. First heard as informal radio broadcasts and then published as three separate books, The Case for Christianity, Christian Behavior, and Beyond Personality, Mere Christianity brings together what Lewis sees as the fundamental truths of the religion.

The End of Faith. The God Delusion. God Is Not Great. Letter to a Christian Nation. Best seller lists are filled with doubters. But what happens when you actually doubt your doubts? Timothy Keller, the founding pastor of Redeemer Presbyterian Church in New York City, addresses the frequent doubts that skeptics, and even ardent believers, have about religion.

In the tradition of Bertrand Russell's Why I Am Not a Christian and Sam Harris' recent best-seller, The End of Faith, Christopher Hitchens makes the ultimate case against religion. With a close and erudite reading of the major religious texts, he documents the ways in which religion is a man-made wish, a cause of dangerous sexual repression, and a distortion of our origins in the cosmos.
