Strobel, who claims to have become a closet atheist (he didn't have the heart to tell his parents and participated half-heartedly in his church confirmation) at age fourteen after learning about evolution in his Illinois high school, was presented with a new challenge when his wife announced that she was committing herself to Christianity. A legal editor at the Chicago Tribune, Strobel had a great deal of experience in investigative journalism, and launched his own investigation to prove to his wife that religion in general and Christianity in particular was a hoax:
To be honest, I didn't want to believe that Christianity could radically transform someone's character and values. It was much easier to raise doubts and manufacture outrageous objections that to consider the possibility that God actually could trigger a revolutionary turn-around. . . .
Instead, after interviewing people at the top of fields such as physics, chemistry, history, and theology, people with doctoral degrees from places like Cambridge and Princeton, Strobel concluded that there is in fact a Creator, and that Jesus of Nazareth was who he claimed to be. In all of his books, including this one, Strobel challenges readers to forget emotion and simply study the evidence, as he did, as he believes readers will come to the same conclusion he did, despite his initial resistance.
