Bestselling author Scott Hahn explains the 'how and why' of the Catholic faith, drawing from Scripture, his own struggles and those of other converts, as well as from everyday life and natural science. Hahn shows that reason and revelation, nature and the supernatural, are not opposed to one another; rather they offer complementary evidence that God exists. Reasons to Believe unravels mysteries, corrects misunderstandings, and offers thoughtful, straightforward responses to common objections about the Catholic faith. It is the ideal book both for Christians who want to grow stronger in their faith and to share it with others, and for enquirers in search of a belief that satisfies both the mind and the heart.
