What does the Bible say about Rahab the harlot?

In the account of Rahab the harlot found in Joshua 2 and 6, she is characterized as a notorious sinner, yet she becomes a vessel of God's mercy. Despite living in a cursed city condemned to destruction, Rahab's faith led her to hide the Israelite spies, and because of this act, she and her family were spared. This narrative powerfully illustrates that God's grace extends to the most wretched sinners, embodying the promise that Christ came to save those who are lost, as noted in 1 Timothy 1:15.
