Why is God's grace significant in the context of sinners?

The significance of God's grace lies in its reach and power to redeem those who are deemed unworthy by the world. As shown in His genealogy, Christ aligns Himself with those who have sinned greatly, including figures like Rahab and David, who both had notable moral failings. This demonstrates that salvation is not based on human merit or lineage, but solely on God's sovereign grace. In God's economy, His mercy towards sinners is magnified, offering hope that no one is beyond the reach of His redemptive love, urging all to come to Him in faith.
