The central message of this sermon is that treasuring Christ, or treating Jesus according to His value, requires recognizing Him and submitting to His presence in our lives. The speaker emphasizes that God's value and excellence are beyond human comprehension, making it essential for us to acknowledge and submit to His sovereignty. This involves paying attention to the signs and workings of God in our lives, asking questions, and surrendering to His will. Ultimately, the sermon encourages listeners to recognize Jesus as their Lord and Savior, receive Him into their lives, and daily surrender to His presence and plans.
