Why is the story of Rahab important in the Bible?

Rahab's actions in hiding the Israelite spies and her declaration of faith in Yahweh mark her as a pivotal figure in Israel's conquest of Jericho. Despite her background, she demonstrates belief in the God of Israel and is rewarded with salvation for her and her family. This exemplifies the overarching theme of God's grace that extends beyond ethnic and social boundaries, inviting those outside the covenant community to be part of His plan of salvation. Her mention in the genealogy of Jesus further emphasizes the inclusiveness of God's grace.
