John Owen emphasizes that the person of Christ serves as the ultimate representation of God and His will, highlighting that while God's essence is incomprehensible to humanity, Christ embodies the divine nature and properties. He argues that all knowledge of God is mediated through Christ, who reveals the Father and fulfills the need for a tangible representation of the divine. Owen asserts that true understanding and worship of God can only be achieved through faith in Christ, as all other attempts to comprehend God lead to idolatry and misrepresentation. The sermon underscores the necessity of Christ's incarnation for humanity to grasp the divine attributes and the importance of recognizing Him as the image of the invisible God. Ultimately, Owen calls believers to seek a deeper relationship with God through the revelation of Christ.
