Why God Chose a Harlot to Save Israel: The Secret of Rahab
What if the only person willing to help you was the one everyone else had written off? What if God chose to work through someone the world had already thrown away? Someone with a broken past, a shameful reputation, and no reason to believe that anything could ever change? What if the very person standing between an entire nation and disaster was a woman that no one expected, living in a city that was about to be destroyed? This is not a story about perfection.
This is a story about faith. Raw, desperate, courageous faith from the most unlikely person in the most unlikely place. Her name was Rahab, and she lived in Jericho. If you’re enjoying this, I encourage you to subscribe. Go ahead and click that button right there.
It just takes a second, and it really helps the channel. The city of Jericho was one of the oldest and most fortified cities in the ancient world. Its walls were massive, thick enough that homes were built right into them. It sat at the edge of Canaan, the land God had promised to his people Israel.
And for the people of Jericho, life inside those walls felt safe, permanent, untouchable. But something had changed in the air. Word had been spreading for years. Stories of a God unlike any other, a God who had split the Red Sea in two, a God who had swallowed Pharaoh’s army in the waters, a God who had led a nation of slaves through a wilderness for 40 years and kept them alive.
The people of Jericho had heard these stories, and deep in their hearts, fear had taken root. Rahab had heard the stories, too. She lived in a house built into the city wall. A woman known by her profession, a woman the city used but did not respect. She was a prostitute. In the eyes of her society, she was at the bottom.
Disposable. Forgotten. The kind of person that religious people walked past without looking at. But God was watching her, and he had a plan. It was a time of great movement. The children of Israel had wandered in the wilderness for 40 years, and now under the leadership of Joshua, Moses’ successor, a man of war and faith, they stood on the eastern bank of the Jordan River.
The promised land was within sight, but between them and their inheritance stood Jericho, powerful, walled, waiting. Joshua knew that before any army marched, he needed information. So, he did what any wise commander would do. He sent spies, two men, quietly, secretly, slipping across the Jordan and into the city of Jericho to scout the land.
And somehow, whether by chance or by the hand of God, and with God there is no such thing as chance, they ended up at Rahab’s house. Think about that for a moment. Of all the places in Jericho, of all the doors they could have knocked on, they came to her. A woman with a broken past. A woman the city had used and discarded.
A woman who, in the quiet of her heart, had been wrestling with something she could not fully explain. A pull toward the God of Israel. A belief that had been growing in her like a fire she could not put out. The spies had barely settled when the king of Jericho received word strangers had entered the city, Israelite men, spies, and they had been seen going into Rahab’s house.
The king sent soldiers immediately. They came to her door with authority and urgency, demanding she hand the men over. Rahab made a choice in that moment, a dangerous, irreversible, life-altering choice. She hid the spies. She had taken them up to the roof of her house and buried them under stalks of flax, long, dry reeds laid out to dry in the sun.
And when the soldiers came knocking, she looked them in the eye and said, “Yes, the men came to me, but I did not know where they were from. And when the gate was about to be closed at dark, the men went out. Where they went, I do not know. Pursue them quickly, for you will overtake them.” The soldiers believed her. They left.
They chased a trail that led nowhere, and Rahab went back up to the roof. Now, here is where the story becomes something extraordinary. Because what Rahab said next to those two hidden men was not the speech of a woman acting on instinct or self-preservation. It was a confession of faith. It was a declaration that had been building inside her for years.
She said to them, “I know that the Lord has given you this land, and that the fear of you has fallen upon us, and that all the inhabitants of the land melt away before you. For we have heard how the Lord dried up the water of the Red Sea before you when you came out of Egypt, and what you did to the two kings of the Amorites who were beyond the Jordan.
And as soon as we heard it, our hearts melted, and there was no spirit left in any man because of you. For the Lord your God, he is God in the heavens above and on the earth beneath.” Read those words again. The Lord your God, he is God in the heavens above and on the earth beneath. This woman, this outsider, this person that the religious world had written off, she had come to a conclusion that many people who grew up in the faith had not yet reached.
She believed not because she had seen a miracle with her own eyes, not because she had walked through the Red Sea. She believed because she had heard, and hearing had produced faith. Have you ever felt like your past disqualifies you from God’s grace? Have you ever looked at your own life and thought, “Surely God cannot use someone like me.” Look at Rahab.
She made one request of the spies. She had risked her life for them. She had chosen their God over her king, their future over her safety, and now she asked for something in return. She said, “Swear to me by the Lord that as I have dealt kindly with you, you also will deal kindly with my father’s house and give me a sure sign that you will save alive my father and mother, my brothers and sisters, and all who belong to them, and deliver our lives from death.”
The spies agreed. They made a covenant with her, and they gave her a sign, a scarlet cord, a crimson thread. She was to tie it in the window of her house, the same window through which she would lower them down the wall to escape when the army of Israel came. Anyone inside the house marked by that scarlet cord would be spared.
She lowered them down through the window with a rope. They disappeared into the night, telling her to hide in the hills for 3 days before the soldiers returned to the city. And Rahab, faithful to the agreement, tied the scarlet cord in her window. Then she waited. Can you imagine what those days were like? The city of Jericho was on high alert.
The gates were shut. Tension was thick in the streets. People were afraid, though they did not fully understand why. And Rahab sat in her house, built into the very wall of the city, with a red cord hanging from her window. A sign that meant nothing to anyone around her, but meant everything to the God of Israel. She had no army.
She had no power. She had no status. All she had was a promise, a cord, and faith. The spies returned to Joshua and reported, “Truly, the Lord has given all the land into our hands. And also, all the inhabitants of the land melt away because of us.” And then God moved. He told Joshua, “See, I have given Jericho into your hand with its king and mighty men of valor.”
The plan he gave was unlike any military strategy the world had ever seen. No battering rams, no siege weapons, no scaling ladders, just priests and trumpets and the ark of the covenant and the people of God walking in silence. For 6 days, the army of Israel marched around the walls of Jericho once each day in silence.
The people of Jericho watched from the walls confused, perhaps mocking. What kind of army was this? What kind of God required marching instead of fighting? But on the seventh day, everything changed. They rose at dawn. They marched around the city not once, but seven times. And on the seventh circuit, the priests blew the trumpets.
Long piercing blasts that cut through the morning air. And Joshua cried out to the people, “Shout! For the Lord has given you the city.” And the people shouted. The sound that rose from the throats of Israel that morning was not just a battle cry. It was worship. It was a declaration. It was the sound of a people who had learned through 40 years of wilderness, through hunger and thirst and failure and grace that their God was faithful.
And the walls of Jericho fell. Not crumbled slowly, not weakened over time. They fell flat, suddenly, completely. The great walls that had made Jericho feel invincible collapsed as if they were made of dust. The army of Israel rushed in from every direction. But one section of the wall still stood. The section where a scarlet cord hung from a window.
Joshua had given the two spies a specific command. “Go into the prostitute’s house and bring out from there the woman and all who belong to her as you swore to her.” And they did. They went to Rahab’s house. They brought out Rahab, her father, her mother, her brothers, and all who belonged to her; every person who had been inside that house under the protection of that scarlet cord was saved alive. The city burned.
The walls were rubble. Jericho was no more. But Rahab lived. The Bible tells us something remarkable about what happened next. Rahab did not simply survive and disappear into history. She was brought into the community of Israel. She lived among God’s people. She was no longer an outsider.
She was no longer defined by her past. She was welcomed, restored, and given a new identity. And then, and this is where the story becomes almost too beautiful to fully take in, Rahab married an Israelite man named Salmon. And they had a son named Boaz. And Boaz married a woman named Ruth. And from that line came a man named Jesse.
And from Jesse came a king named David. And from the line of David, centuries later, came Jesus Christ, the Son of God, the Savior of the world. Rahab, the prostitute of Jericho, is in the bloodline of Jesus. Let that settle over you for a moment. God did not just save Rahab. He wove her into the very story of redemption.
He placed her in the lineage of the one who would come to save all of humanity. The woman the world had thrown away became an ancestor of the one who came to save the world. This is who God is. Now, what does this story mean for you today? The first lesson is this. Faith is not about your past. It is about your response to what you know about God.
Rahab had no Torah. She had no temple. She had no priest. She had heard stories. And she believed. The book of Hebrews in its great hall of faith lists Rahab by name. By faith Rahab the prostitute did not perish with those who were disobedient, because she had given a friendly welcome to the spies.
She is listed alongside Abraham, Moses, and Noah. Not because she was perfect, but because she believed and she acted on that belief. Faith without action is not faith at all. Rahab’s faith moved her hands. It made her hide the spies. It made her tie the cord. It made her wait. Real faith always moves. The second lesson is this.
God sees people that the world overlooks. The religious leaders of Jericho did not make it into the story of salvation. The king did not. The soldiers did not. A woman that society had discarded—she is the one God chose. If you have ever felt invisible, if you have ever felt like your mistakes have put you beyond the reach of grace, hear this clearly.
God is not looking for the most impressive person in the room. He is looking for the person who will believe him and act on that belief. He has always worked through the unlikely. He still does. The third lesson is this. The scarlet cord is a picture of the blood of Jesus. This is not a stretch of theology.
It is a thread that runs through the entire Bible. The cord was scarlet. Red. The color of blood. And it was the only thing that stood between Rahab’s household and destruction. When the judgment came, the cord was the sign of protection. In the same way, the blood of Jesus Christ is the only thing that stands between any of us and the judgment we deserve.
Just as Rahab had to stay inside the house marked by the cord, we must remain in Christ. Covered by his blood. Sheltered by his grace. Outside of that covering, there is no safety. Inside of it, there is complete protection. The fourth lesson is this. It is never too late to change sides. Rahab lived in Jericho.
She was part of a city that was under judgment. But she made a choice. She chose the God of Israel over the king of Jericho. She chose faith over fear. She chose the future over the familiar. And that choice cost her everything she had known, and gave her everything that mattered. You may be living in a world that is moving in the wrong direction.
You may be surrounded by people who have no interest in God. But you can make a choice today. You can tie the cord. You can say, like Rahab said, “The Lord your God, he is God in the heavens above and on the earth beneath.” And that choice will change everything. There is one more thing worth saying.
In the book of James, when the writer wants to give an example of faith that works, faith that is real and active and alive, he does not only use Abraham, he uses Rahab. He says, “Was not also Rahab the prostitute justified by works when she received the messengers and sent them out by another way?” God preserved her story in scripture not as a footnote, but as a testimony.
Her life is proof that no one is too far gone. No past is too broken. No reputation is too damaged for the grace of God to reach. The walls of Jericho fell, but Rahab’s house stood. And it stood because of one thing, a scarlet cord tied in faith in a window on a crumbling wall. Whatever your walls look like today, whatever has been built up around your life, whatever shame or fear or failure has made you feel trapped, know this, the same God who saw Rahab in that city sees you right now.
He is not looking at your past. He is looking at your heart. He is asking the same question he asked through the spies at her door, “Will you trust me? Will you believe? Tie the cord. Step into faith and watch what God can do with a life that is fully surrendered to him.”
