In 1998, Lee Strobel, a reporter for the Chicago Tribune and a graduate of Yale Law School, published “The Case for Christ: A Journalist’s Personal Investigation of the Evidence for Jesus.” Strobel had formerly been an atheist and was compelled by his wife’s conversion to evangelical Christianity to refute the key Christian claims about Jesus. Paramount among these was the historicity of Jesus’ resurrection, but other claims included the belief in Jesus as the literal Son of God and the accuracy of the New Testament writings. Strobel, however, was unable to refute these claims to his satisfaction, and he then converted to Christianity as well. His book became one of the bestselling works of Christian apologetic of all time.
