Today this message [to repent and turn to God] is vital to the eternal destiny of not only ethnic children of Abraham, the Jews, but also that largest of hidden people groups, nominal Christians. If 75-80 percent of the world’s Christians are Christian in name only, then one billion people need to be awakened out of their “smug assurance of salvation by biological birthright.”
