Each year one-third of the entire world population observes Christmas. Two billion people celebrate that a Child was born in a manger 2,000 years ago. They decorate their homes inside and out, put up Christmas lights, and exchange gifts. They send cards expressing the joy of the occasion, and sing popular Christmas carols, such as “Hark! The Herald Angels Sing.” Yet comparatively few truly understand the meaning of that famous hymn—that Jesus was “born that man no more may die.” “Christmas Gone Viral” is a unique and fascinating explanation of that wonderful truth.
