The Apostle Paul at one time defined faith as the evidence of things not seen. The Book of Mormon is solid, tangible evidence of both the seen and the unseen.

It is a book that can be felt and handled and read. It is a physical object. It cannot be explained out of existence. The critics cannot make it go away. As a published book it is here—tangible, physical, and material. – Mark E. Petersen, “Evidence of Things Not Seen,” Ensign (CR) May 1978
