In Reasons to Believe, Scott Hahn, a convert to Catholicism, 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 even natural science. Hahn shows that reason and revelation, as well as nature and the supernatural, are not opposed to one another; rather, they offer complementary evidence that God exists. He is someone, and He has a personality, a personal style, that is discernible and knowable.

Hahn leads readers to see that God created the universe with a purpose and a form—a form that can be found in the Book of Genesis and that is there when we view the natural world through a microscope, through a telescope, or through our contact lenses.

At the heart of the book is Hahn's examination of the ten "Keys to the kingdom"—the characteristics of the Church clearly evident in the Scriptures. As the story of creation discloses, the world is a house that has a Father, a palace where the king is really present. God created the cosmos to be a kingdom, and that kingdom is the universal Church, fully revealed by Jesus Christ.
