Rehab's faith resulted in a total transformation in her life.
A new God - As a result of her faith, this Canaanite woman entered into the Jewish faith. It is similar to her future great granddaughter-in-law, Ruth the Moabitess would say to Naomi: "thy people shall be my people, and thy God my God" (Ruth 1:16). A new God and a new revelation.
A new husband - A woman with no husband married to a man named Salmon, Matthew 1:5-6.
A new generation - She had been a heathen, a non-believer, but found favor with God because of her faith, which was shown by her works. Rahab's faith resulted in blessing for the world. She became one of the ancestors of our Lord Jesus Christ.
