Spurgeon was considered by many to be the greatest preacher of his generation and lived during the nineteenth-century revival of the celebration of Christmas in America and England. He loved Christmas and welcomed the holiday season as an opportunity for rest and being reunited with friends and family.

How can Christians properly celebrate Christmas today? Certainly, Christmas trees, gift-giving, family reunions, and many other customs can all be joyful traditions of the season. But Spurgeon would say that the primary way to celebrate Christmas is by faith in the incarnate, crucified, and risen Savior. That's why A Wondrous Mystery exists: amid a busy holiday season, it is meant to be a daily reminder of why we celebrate--that "the Infinite has become an infant" and "the joy of his coming is still in our hearts."
