Shane Idleman emphasizes the true meaning of Christmas in his sermon 'Name Him and Claim Him,' warning against the misinterpretation of the 'Name It and Claim It' gospel that promotes a prosperity mindset. He highlights the importance of understanding Jesus' names from Isaiah 9:6, which reflect His true nature as Wonderful Counselor, Mighty God, Everlasting Father, and Prince of Peace. Idleman encourages believers to claim the promises of God, especially during difficult times, and to remember that faith should lead to a deeper relationship with Christ rather than a transactional mindset. He stresses the need for genuine faith that acknowledges Jesus as Savior, not just a historical figure, and calls for a heart transformation through repentance and acceptance of Christ's sacrifice. The sermon concludes with a reminder of the significance of communion as a reflection of Jesus' love and suffering.
