James 2:24

You see that a man (believer) is justified by works and not by faith alone (that is, by acts of obedience a born-again believer reveals his faith). In the same way, was Rahab the prostitute not justified by works too, when she received the spies as guests and protected them, and sent them away (to escape) by a different route?

Rahab believed the Hebrew spies’ promise to protect her family. She acted on that promise and placed a red cord out the window, saving her family. How much more the promise remains for us when we believe Jesus at His word and act in faith?
