What Rahab Knew

The sermon centers on Rahab the harlot in Joshua 2, presenting her as a profound example of God’s redemptive heart toward the marginalized and outcast. Through her recognition of God’s sovereign power—evident in the parting of the Red Sea and the conquest of Sihon and Og—Rahab demonstrates a faith that aligns with divine reality, unlike the false security of Jericho’s walls or the deceptive tactics of the Gibeonites. Her true knowledge leads not only to desperate appeal and immediate action—such as tying the scarlet cord in her window—but also to a life fully committed to God’s people and purposes, reflecting the regenerate heart of a believer. The sermon confronts the tension of her deception by affirming that her faith, not her moral perfection, was reckoned as righteousness, pointing to Christ’s saving work on Calvary where even the thief was welcomed. Ultimately, Rahab’s inclusion in Christ’s lineage underscores God’s sovereign grace, revealing a divine heart that pursues the lost, transforms the unworthy, and glorifies Himself through the redemption of the most unlikely, calling believers to live with urgent faith, compassion, and a burden for the spiritually destitute.
