Norman Leo Geisler was born on July 21, 1932, in Warren, Michigan, a suburb of Detroit. He attended a nondenominational Evangelical church from age nine but was not converted until the age of eighteen. He immediately began attempting to share his faith with others in various evangelistic endeavors—door-to-door, street meetings, and jail service, rescue missions, and Youth for Christ venues. Some of his conversations forced him to realize that he needed to find better answers to the objections he was hearing. He subsequently earned two bachelor's degrees, two master's degrees, and a Doctorate.
