“I know that the LORD has given you the land, and that the fear of you has fallen upon us…. For we have heard how the LORD dried up the water of the Red Sea before you when you came out of Egypt…And as soon as we heard it, our hearts melted…because of you, for the LORD your God, he is God in the heavens above and on the earth beneath” (Joshua 2:9-11). These words were spoken by the most famous prostitute in the Bible…Rahab. This woman, despite her illicit trade, is commended in the Bible for her faith. Matthew points out that Rahab is a great, great grandmother of Jesus. She is listed among the heroes of Faith in Hebrews 11. James also referred to her as a role model of what it means to believe in God. Rahab spoke the words cited above in the biggest crisis of her life. She had lived a life of idolatry and sexual promiscuity. She had used her body to feed the lusts of many men, giving them a brief period of pleasure at great cost to them, to their marriages, and to their families. However, in the recent past, she had heard news about a large nation that was advancing in the direction where she lived. They were now camped on the other side of the River Jordan, and any day now they would cross over in precisely the same way they crossed the Red Sea. This nation, the nation of Israel, had destroyed the military might of Egypt when they escaped the clutches of Pharaoh. They had destroyed every nation along the way that had resisted them. Now they were knocking on the door of Jericho. Rahab trembled. In this crisis, Rahab had done a lot of thinking and reached the conclusion that the gods her people worshipped were not real. There was only one true God in the whole universe. It was the God who was worshipped by the nation of Israel. He is the one who gave Israel victory. Rahab went further. She decided to switch sides, for dear life’s sake. Hence, she hid the spies who came from Joshua, even when she knew that their success would mean the destruction of her own people. She only asked that her life and the lives of her close relatives be spared. What do we learn from this woman? It is the fact that true faith proves itself through action. Hebrews 11:31 says, “By faith Rahab the prostitute did not perish with those who were disobedient, because she had given a friendly welcome to the spies.” She acted on her faith! No doubt, Rahab must have given up her illicit trade upon getting to know this God who was a moral God and who demanded that sex should only be done in the context of marriage. Are you a believer? Look at your life. Do your actions prove that you know God?
