Dr. Adler, in his discussion, extends and modernizes the argument for the existence of God developed by Aristotle and Aquinas. Without relying on faith, mysticism, or science (none of which, according to Dr. Adler, can prove or disprove the existence of God), he uses a rationalist argument to lead the reader to a point where he or she can see that the existence of God is not necessarily dependent upon a suspension of disbelief. Dr. Adler provides a nondogmatic exposition of the principles behind the belief that God, or some other supernatural cause, has to exist in some form. Through concise and lucid arguments, Dr. Adler shapes a highly emotional and often erratic conception of God into a credible and understandable concept for the lay person. -- Publisher's description.

Richard Rohr focuses his attention on all frames and doorways to the divine--the alternative way of Francis of Assisi. Francis of Assisi, one of the most beloved of all saints, was at once very traditional and entirely revolutionary in the ways of holiness. As a standing paradox, he both stood barefoot on the earth and yet touched the heavens; he was grounded in the church and yet instinctively moved toward the cosmos; he lived happily inside the visible and tangible, and yet both suffered and rejoiced in the invisible. Rohr places the tradition as first practiced by Francis, and subsequently by others, within a context for the uninitiated audience. This is not a historical accounting, but rather a perspective about how the alternative orthodoxy can deepen spiritual life for anyone, whether Catholic, Protestant, Jewish, secular, or spiritual seeker. Eager to Love is grounded in the Gospels, the prophets, a broad blend of psychology and theology, and in literature and art, to continue to communicate through all the sources that articulate specific alternative ways of understanding God with us.

Lee Strobel guides readers on a rigorous investigation into the evidence for Jesus as the Son of God, challenging scholars and examining historical, textual, and scientific arguments.
