The sermon centers on the divine name 'Wonderful' ascribed to Christ in Isaiah 9:6, emphasizing that this title captures His incomparable nature—far surpassing human language or experience. It explores Christ's wonder in His person, as the eternal Son who is both fully God and fully man, uniquely incarnate and sinless, whose life, teachings, and miracles reveal a divine majesty that defies human comprehension. The message underscores that His wonder is not merely in His works but in His very being—eternally begotten, co-equal with the Father, and the Creator of all things—making Him the ultimate object of awe and worship. The sermon also highlights how this wonder is revealed in salvation history: in the humble announcement to shepherds, the rejection by worldly powers, and the transformative grace that renews sinners, as seen in the believer's transformation described in 1 Corinthians 6. Ultimately, it points to the future, when Christ will return as Judge and Savior, and all creation will acknowledge His wonder—those in glory singing His praise, while the lost cry out in despair, leaving every listener with a stark choice: to reject or to affirm the truth of His greatness.
