God spared the lives of Rahab and her household because of her faith. Any of Rahab’s relatives that would have gathered with her before the Israelite siege would have done so because of their faith in God’s promise through the spies. If they had no faith they would have stayed in their own homes. Thus the deliverance of Rahab and her family depended on believing a promise from God. Salvation always depends on believing a promise from God (cf. Genesis 15:6; John 3:16; et al.).
