Rahab Was a Prostitute. God Used Her. Your Sexual Sin Doesn’t Have To Disqualify You.

God used a prostitute to bring forth a King—what’s your excuse?

When we think of those honored in God’s story, a prostitute likely isn’t the first name that comes to mind. Yet Rahab the harlot stands boldly in the lineage of Jesus Christ—not because of her past, but because of her faith. Her story forces us to confront a tension many shy away from: how can someone so entangled in sexual sin be called righteous? From fornication and lust to prostitution and affairs, the Bible is clear—sexual sin separates us from God. And yet, the story of Rahab reveals something deeper: God doesn’t approve of sin, but He honors faith that turns toward Him. Her transformation wasn't based on cleaned-up behavior first, but on a surrendered heart that chose Him even while surrounded by compromise. This isn’t just a rescue story—it’s a prophetic glimpse into redemption itself.

Sexual sins, in Scripture, are consistently named among the most defiling acts because they involve the body—the temple of the Holy Spirit (1 Cor. 6:18-20). These include:

• Fornication – sex outside of marriage

• Adultery – sexual betrayal of a covenant

• Masturbation & Lust – inward sexual indulgence of the flesh (Matt. 5:28)

• Prostitution – the selling of one’s body for sexual gain

• Homosexual acts – contrary to God's created design for marriage (Rom. 1:26–27; 1 Cor. 6:9-11)

• Pornography  – the feeding of lust through visual stimulation, which fuels the above sins.

Sexual sin distorts the image of God in us. It hijacks intimacy meant for covenant and trades it for momentary pleasure or power. It often leaves behind shame, soul ties, and spiritual defilement. God is not silent about sexual sin—He calls it sin, not to condemn, but to invite us into freedom.

Rahab the Harlot: A Scandalous Exception or a Prophetic Sign?

When Rahab first appears in tjerichohe pages of Scripture, there’s no sugarcoating her identity: “Rahab the harlot” (Joshua 2:1). She lived in Jericho—a fortified city steeped in idolatry, destined for destruction under God’s judgment. Her home was literally built into the city wall, and her profession—prostitution—was considered among the lowest and most defiling by Israelite standards. She was, by all accounts, an outsider to the covenant, both morally and nationally.

But while Jericho feared Israel’s army, Rahab feared Israel’s God.

“We have heard how the Lord dried up the water of the Red Sea... for the Lord your God, He is God in heaven above and on the earth beneath.” — Joshua 2:10–11

In the midst of a pagan city, Rahab had been listening. She’d heard the stories—of Egypt’s collapse, of Red Sea miracles, of the God who fought for His people. And unlike her fellow citizens who hardened their hearts, she responded with trembling belief. Her fear wasn’t of men—it was of the true and living God.

So when two Israelite spies entered Jericho to scout the land, Rahab saw an opportunity. She welcomed them, hid them on her roof, lied to protect them, and negotiated the safety of her family. Why would she do this? Because faith had already begun to grow in her heart, and she was choosing sides—leaving behind her culture, her gods, and her comfort to side with Yahweh.

Her actions weren’t merely brave—they were prophetic. She wasn’t just helping spies; she was helping God’s purpose move forward. She became a pivotal part of God’s plan to take the Promised Land. And Hebrews 11:31 makes it clear:

“By faith the harlot Rahab did not perish with those who were disobedient, because she had given a friendly welcome to the spies.”

Her righteousness was not born from moral perfection, but from a decisive, faith-filled pivot. She believed—before she belonged. And that belief turned into action, just as it did with Abraham, who was also counted righteous by faith (Romans 4:3). Rahab’s help to the spies was more than an act of kindness—it was an act of alignment with the God of Israel. Her life had pivoted inwardly long before Jericho’s walls ever fell.

Was There Evidence of Her Change?

Rahab had a past. Grace gave her a future.

We don’t need to read far to see it. After Jericho fell, Rahab and her family were rescued and brought into the camp of Israel (Joshua 6:25). This was more than a rescue—it was adoption. She became a full member of God’s people. Tradition and genealogy reveal something remarkable: Rahab married Salmon, a Hebrew man of noble lineage, and gave birth to Boaz—the same Boaz who would marry Ruth, a Moabite woman who also sought refuge under the wings of the God of Israel. And from that line came David, and eventually Jesus (see Matthew 1:5–6). A former prostitute not only received mercy—she became part of the Messiah’s story.

What Is God Saying Through Rahab’s Story?

God does not celebrate sexual sin—but He redeems sinners. He never endorsed Rahab’s profession, yet He honored her faith. Her righteousness wasn’t rooted in what she did with her body, but in what she chose to do with her heart. She aligned herself with God, not because she had already cleaned up her life, but because she believed He was the one true God. That belief moved her to act, and that action revealed a heart already turning.

Joshua 2:11 (NKJV):“And as soon as we heard these things, our hearts melted; neither did there remain any more courage in anyone because of you, for the Lord your God, He is God in heaven above and on earth beneath.”

This is Rahab’s confession of faith. Surrounded by a pagan culture in Jericho, steeped in idol worship, Rahab stands out by declaring the supremacy of Israel’s God. She doesn’t say “your god is strong”—she says He is God, in heaven and on earth. This moment mirrors the heart of Romans 10:10:

“For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.”

Rahab’s words weren’t just fear—they were faith. She believed God was not one god among many—He was the only God, and she staked her life and her family’s future on it. That’s why Hebrews 11:31 lists her alongside Abraham, Moses, and the greats of faith.

She wasn’t cleaned up first—she was called first.

God always calls people out of sin, never to remain in it—but in His mercy, He meets them in the middle of it. Rahab’s story is not one of God overlooking sin, but of Him overpowering it with redemption for the one willing to turn and trust.

Faith breaks generational cycles and births new legacies. Rahab’s past did not define her future, nor did her former identity limit what God could do through her. After being rescued and welcomed into the family of Israel, she married Salmon and gave birth to Boaz—a man known for his integrity, strength, and compassion. This same Boaz would one day marry Ruth, another outsider who sought refuge under the wings of the God of Israel. Through Rahab’s story, we see the power of grace not just to save a person, but to rewrite an entire bloodline. Her faith silenced shame and laid the foundation for a godly legacy that would ultimately bring forth King David—and generations later, Jesus the Messiah.

God’s mercy reaches where man’s judgment stops. While Israel would have never chosen Rahab as a “worthy vessel,” God saw beyond her reputation and into her heart. Where others saw a harlot, He saw a woman ready to believe and obey. In the same way Jesus responded to the woman caught in adultery, God stooped low—beneath the weight of shame, beneath the labels—to lift Rahab into a place of honor. He didn’t excuse her sin, but He extended mercy that reached further than human eyes were willing to look. Rahab’s story reminds us that God’s choosing often defies religious expectations, and His grace touches those we might be quick to dismiss.

Sexual sins are forgivable—but not excusable. Rahab didn’t continue in her old life once she aligned herself with God; she left it behind. Rahab wasn’t just rescued and left on her own. She was brought into the camp of Israel and lived among them as one of their own.

Joshua 6:25 (NKJV):“And Joshua spared Rahab the harlot, her father’s household, and all that she had. So she dwells in Israel to this day, because she hid the messengers whom Joshua sent to spy out Jericho.”

This verse confirms that Rahab didn’t return to Jericho (which was destroyed), nor did she go back to her old lifestyle. Instead, she was grafted into Israel, just like Ruth would be later. Living in the camp of Israel would have required Rahab to abandon pagan worship, idolatry, and sexual immorality, all of which were condemned under the Mosaic law.

God didn’t overlook her prostitution—He overshadowed it with redemption. He didn’t pretend it never happened, but He rewrote her story so that her past no longer held the final word. That’s the power of grace—it doesn’t excuse the sin, it defeats it. This is key: true faith doesn’t let us stay in sin. It pulls us out of it, compels change, and produces fruit that proves repentance. Rahab’s life is a living testimony that no matter how dark the beginning, a surrendered heart can be transformed by the light of God’s mercy.

She sold her body—then gave God her heart.

Rahab’s story isn’t just about prostitution—it’s a mirror for every person caught in sexual sin, whether it’s fornication, adultery, lust, masturbation, pornography, or same-sex relationships. God does not play favorites. As Romans 2:11 declares,

“For there is no respect of persons with God.”

 The same mercy that called Abraham out of idolatry and counted him righteous by faith (Romans 4:3) is the same mercy that reached into the house of a harlot and rewrote her future. And it’s the same grace available to you. God's Word doesn't excuse sexual sin—it exposes it so it can be healed. His grace is not a license to remain in bondage but an invitation to be made new.

“But He said to me, ‘My grace is sufficient for you, for My strength is made perfect in weakness.’” — 2 Corinthians 12:9

Like Rahab, you don’t have to be clean to come to God—you come to God because you need to be made clean. Her freedom came after her act of faith, not before. She surrendered while still surrounded by her old life, and it was that faith, not her perfection, that marked her righteous. If you’re still in the muck, still wrestling, still entangled—don’t wait. Turn now. Trust Him now. The same God who welcomed Rahab and walked with Abraham will do no less for you. His grace is sufficient. His mercy is ready. And your story can be rewritten.

Rahab didn’t just believe—she changed. Her faith wasn’t just words; it was movement. James 2:25 points to her as proof that real faith produces real transformation: James 2:24–26 (ESV):

You see that a person is justified by works and not by faith alone. And in the same way was not also Rahab the prostitute justified by works when she received the messengers and sent them out by another way? For as the body apart from the spirit is dead, so also faith apart from works is dead.

From scandal to legacy—Rahab proves God writes better endings.

She was known by her past, but she wasn’t chained to it. Rahab left behind her city, her culture, and her profession. She stepped into a new life, joined God’s people, married into the covenant, raised a godly son, and became an honored ancestor of Jesus Himself. If you’re caught in the web of sexual sin—lust, pornography, adultery, same-sex relationships, prostitution, or any other form of compromise—Rahab’s story stands as a beacon of hope.

You don’t have to stay stuck. Your faith can pull you out. God doesn’t ask you to be perfect before you come—He calls you to believe, and then follow. Like Rahab, let your faith be more than a feeling—let it lead you out of sin and into legacy. The same God who rewrote her story can rewrite yours. All He needs is your yes.
