Big Idea: God uses whoever is willing to glorify Himself and bring us into the purpose and destiny for which He has made us (Eph. 2:10).
II. The Faith of Rahab
A. She recognized God for who He was despite her location and polytheistic culture (2:9). What is important about her recognition is that she calls Him by His personal name, Jehovah which speaks to God’s “the independent and self-existent God of revelation and redemption.” (Bible.org)
B. Rahab recognized God’s hand upon Israel and His mighty miraculous works on their behalf for His divine purpose (2:10-11). We know that Israel struggled with responded in faith to God’s miraculous deeds on their behalf. But Rahab, an idolater and prostitute, responds in faith to what God has done. It is no wonder that she is listed in the Hall of Faith in Hebrews 11:31.
C. Rahab trusted God to save her AND her entire family. The rest of the chapter shows a woman willing to risk her own life and household on the belief that the God of Israel would preserve them. Like the blood over the door post for Israel, the scarlet thread represents the coming Christ whose very blood would deliver those who place their faith in Him. Where the thread was, so too was the protection. Remember: this prostitute was ready to risk EVERYTHING for a God she did not serve who led a people who could have easily destroyed.
