In her New York Times bestsellers Going Rogue and America by Heart, Sarah Palin revealed the strong Christian faith that has guided her life and family. In Good Tidings and Great Joy she calls for bringing back the freedom to express the Christian values of the season. She asserts the importance of preserving Jesus Christ in Christmas—in public displays, school concerts, pageants, and our expressions to one another other—and laments the over-commercialization and homogenization of Christmas in today's society.

Interwoven throughout are personal memories and family traditions, as well as more than a dozen family photos, which illustrate the reasons why the celebration of Jesus Christ's nativity is the centerpiece of her faith. Palin believes it is imperative that we stand up for our beliefs before the element of faith in a glorious and traditional holiday like Christmas is marginalized and ignored. She also encourages readers to see what is possible when we unite in defense of our religious convictions and ignore the politically correct Scrooges seeking to take Christ out of Christmas. Good Tidings and Great Joy is a call to action to openly celebrate the joys of Christianity, and say Merry Christmas to one another.
