What does the Bible say about Rahab's salvation?

The story of Rahab, as told in Joshua 2, illustrates the sovereign grace of God in saving individuals who may otherwise seem unworthy. Rahab was a Gentile and a sinner, yet she was chosen by God to be saved because of her faith. This act of salvation signifies that God's grace is not limited by a person's past or social standing. As Rahab believed in the God of Israel after hearing of His mighty acts, it shows that faith comes through hearing the word of God, which is consistent with how God calls His elect, regardless of their background. Rahab's inclusion in the genealogy of Christ further underscores the point that God's plan of salvation extends to all who believe in Jesus Christ.
