How does the law lead us to recognize our need for a mediator?

As seen in Exodus 20:19, the people of Israel recognized their sinful state when confronted with God's holy law and requested Moses to speak on their behalf. This reflects the reality that the law itself exposes our shortcomings and reveals our utter inability to achieve righteousness through our efforts. The demand for absolute obedience leaves humanity in a position of despair and underscores the necessity for a mediator. In Christian theology, Jesus Christ fulfills this role perfectly, bridging the gap between a holy God and sinful man by offering Himself as the ultimate sacrifice, allowing believers to approach God with confidence.
