This book is written in three parts. PART ONE is about the basic concepts of Christianity, including free will, revelation, faith, symbol, time and death and God's offer to us of life. PART TWO is about the stuff of God, which is the way that God enters into the world through creation and the way he works through the world to bring man to God. Here we find the centrality of symbol and sacrament in connecting our physical life to the spiritual life of God. PART THREE is about the central moral problem of our age, which is the liberation of the human body from any relationship with God. A body free from God is a body with need for the resurrection and connection with Christianity.
