Atheists deny we can know God because they deny there is a God to know. But even believers who affirm God's existence sometimes don't know him. They don't know much about God because they neglect to think much about God and what God has revealed about himself. They accept that there is a God but they don't give much thought to what God is like. And even if they know a great deal about God in the sense of being able to state truths about him, they don't necessarily know him personally and intimately.

In Knowing God (previously titled God and the Human Mind) the great Catholic writer, teacher, and publisher Frank Sheed helps readers to know that God exists, to think about who and what God is, and to know God personally. He clears away popular misunderstandings of God, often held by otherwise knowledgeable people. A masterful, lucid writer, Sheed is not timid about tackling the most challenging questions the human mind can pose about God, yet he does not reduce divine mystery to dry propositions or neglect the necessity of faith.

Sheed acknowledges the limits of human words and human minds when it comes to God. At the same time, he carefully explains the meaning of Spirit, the role of theology and revelation, including the place of the Bible in the Church, and the experience of God in mysticism. In the final section, Sheed goes into the heart of the mystery of God, exploring God as the Trinity and the difference the Trinity should make in understanding God and ourselves.

"This book is vintage Sheed: clear, commonsensical, and convincing. This is the Sheed of the two masterpieces of apologetics Theology and Sanity and Society and Sanity. But this is also a new Sheed: older and wiser, more practical and human--the post-Vatican II Sheed. I mean this in all the good senses, the John Paul II senses: he is sensitive to the dangers of "the good old days": verbalism, "dead orthodoxy," rationalism, deism, what Sheed calls "theometry" instead of theology: an abstract, formal theological geometry that only wants to define terms and win debating points. Instead, this book is a kind of theological midrash, a deepening, a spelunking in the caves of the deepest mysteries with the clear light of honest words--honest with heart as well as head. It unites dogmatic theology with lived religion. It is precisely the breath of fresh air that Pope John XXIII opened the windows for, and in terms the layman "can clearly grasp.

"No human activity is more important than knowing God, and few human beings have explained how to go about it better than Frank Sheed did in Knowing God. If you really want to love God, you must know Him. And if you really want to know Him, you must read this book."
