H.J. Vine emphasizes the profound wisdom of God as revealed through Christ in Isaiah, illustrating how the Servant of the Lord embodies divine wisdom and purpose. He contrasts the expectations of the mere religionist and the rationalist, showing that true wisdom is found in Christ, who suffered and was exalted for our salvation. The sermon highlights the significance of Christ as the true Israel and the faithful Servant, who restores and brings light to all nations. Vine also reflects on the prophetic nature of Isaiah, affirming that Christ's atoning work fulfills God's promises and secures salvation for both Israel and the Gentiles.
