James 2:24-25

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 [Hebrew] spies as guests and protected them, and sent them away [to escape] by a different route? [Josh 2:1-21]
