Welcome Detweiler emphasizes the significance of Christmas Day as a time for joy and reflection on the true meaning of Christ's coming. He contrasts the superficial celebrations of the unsaved with the deep adoration of believers who understand that Jesus, the Word made flesh, came to redeem humanity through His sacrificial death. Detweiler reminds us that the essence of Christmas is not merely in the celebration of His birth but in recognizing the purpose of His coming, which culminates in His death and resurrection. He urges listeners to present themselves to Christ as the ultimate gift, highlighting that true satisfaction and peace come only through Him. The sermon concludes with a call to both believers and the unsaved to embrace Christ and find joy in their relationship with Him.
