How does the Sermon on the Mount relate to grace?

In the Sermon on the Mount, Jesus presents a radical redefinition of righteousness that goes beyond mere external obedience to the law. He exposes the true nature of sin by addressing the heart’s intentions and motivations. For instance, He equates anger with murder and lust with adultery, highlighting the impossibility of achieving this standard through human effort alone. Therefore, understanding grace becomes essential, as it is through faith in Christ that we receive the righteousness needed to meet these divine standards. Grace enables us to navigate the challenges of living out this calling not by our strength but through reliance on the Holy Spirit.
