It might seem odd to you that today’s reading is about Rahab helping the spies. What does that have to do with Jesus? A great deal, as we remember the many times that Rahab is mentioned in the New Testament.
We first see Rahab’s connection to Jesus in the genealogy of Matthew: and Salmon the father of Boaz by Rahab, and Boaz the father of Obed by Ruth, and Obed the father of Jesse (Matt. 1:5). She was the great, great grandmother of King David! Rahab herself is in the line that led to Jesus. Matthew includes this woman of questionable background because of her faith, since God used her to save the spies. The author of Hebrews says just that. By faith Rahab the prostitute did not perish with those who were disobedient, because she had given a friendly welcome to the spies (Heb. 11:31). Rahab showed her faith by helping the spies, as James tells us (James 2:25).
Rahab made it possible for God’s people to enter the Promised Land, to have David as their king, and to eventually have Jesus as a descendant of David. All this was done by the grace and plan of God, through his faithful servant.
