How do we know that Christ is the only one who meets God's perfect standard?

The sermon emphasizes that the standard set forth in Psalm 15 cannot be met by any person except Jesus Christ. He alone walks uprightly, works righteousness, and speaks the truth from His heart. Unlike us, whose truth is often mixed with error, Christ is entirely pure and embodies truth itself. His fulfillment of the Law not only validates His role as our Savior but also highlights our need for His righteousness, as no one else can meet the perfection required to enter into God’s presence. We are reminded that our hope is not in our efforts to attain perfection but in Christ’s completed work.
