How do we know God's grace can save even the worst sinners?

Spurgeon reminds us that no soul is beyond the reach of God's grace, citing the omnipotent work of the Holy Spirit. He emphasizes that all humanity is born in sin, as seen in Romans 3:10-12, where it states that 'There is none righteous, no, not one.' This creates a foundation for understanding that grace is not based on human merit but on God's sovereign choice to extend mercy. The grace that rescued us can similarly transform the most vile and sinful among us, showcasing God's magnificence and the depth of His love.
