Why is it important for Christians to recognize the futility of their works?

In the sermon, the preacher explains that attempting to come to God through our own works is futile. The kingdom of flesh relies on human strength, religious rituals, and morality, which are inadequate for reconciliation with God. Isaiah 1:12-14 illustrates this by showing that the Lord rejects vain oblations and hypocrisy. Only through Jesus Christ can we achieve the righteousness needed to stand before God. This understanding drives believers to flee from the flesh and lean solely on the sufficiency of Christ's sacrifice. As we grapple with our sins and inability to appease God through our efforts, we are directed toward the hope found in Christ's completed work, affirming the essential role of grace in salvation.
