What does the Bible say about notorious sinners like Rahab?

In Joshua 2, Rahab is introduced as a notorious sinner, labeled 'Rahab the harlot.' Her story illustrates that in God's sight, all humanity is guilty of sin and in need of salvation. Despite her past, Rahab demonstrates faith in the God of Israel, recognizing His sovereignty and power. The New Testament continually refers to her, emphasizing that her faith, amidst her notorious background, earned her a place in the lineage of Christ and highlighted God's grace for sinners. This underscores the biblical truth that God's grace and mercy extend to all, no matter their past sins.
