Pastor Spencer Harmon reveals "the great Christmas tradition" from John 20:21—a biblical tradition Jesus himself instituted that's often neglected during the holiday season.

Learn the three essential elements in this powerful Christmas sermon that will transform how you celebrate the season and may reveal God's specific calling for your life—whether in local ministry, full-time Christian service, or overseas missions.
