God's Faithfulness: From Joshua to Rahab

Devotional

Day 1: Scarlet Rope in the Window

Joshua sent two spies across the Jordan under night’s cover. Their sandals crunched Jericho’s streets until they ducked into a house marked by a faded scarlet thread. Rahab hid them under flax stalks as soldiers pounded her door. “They left at dusk,” she lied, her hands steady. Her treason wasn’t for strangers—it was for the God who parts seas and shatters kings. [30:03]

Rahab gambled everything because she recognized Yahweh’s fingerprints on history. While her city trembled at Israel’s approach, she saw past the fear to the faithfulness of a God who keeps covenant. Her flax stalks became an altar—her lie an act of war against the gods of Jericho.

When has God asked you to stake your safety on His character? What “flax stalks” hide your quiet acts of obedience to Him? Write down one promise of God you’re tempted to doubt. Where is He calling you to tie your scarlet rope today?

“By faith Rahab the prostitute did not perish with those who were disobedient, because she had given a friendly welcome to the spies.”
(Hebrews 11:31, ESV)

Prayer: Ask God to expose areas where you still cling to self-preservation over radical trust.
Challenge: Text one person today: “How can I pray for your Jericho-sized fear this week?”

Day 2: Flax Stalks and Foolish Spies

The spies crouched under drying flax, its earthy scent masking their sweat. Joshua’s orders had been clear: “Scout the land.” But their mission now hung on a prostitute’s courage. Rahab’s rooftop confession—“Your God is God”—echoed louder than Jericho’s walls. They returned with no battle plans, just a redeemed soul and a scarlet thread. [28:11]

God used bungling spies to rescue a woman from judgment. Their failure to stay hidden became the crack through which grace flooded. Jericho’s military secrets didn’t matter—Rahab’s heart did. What seemed like wasted reconnaissance was divine appointment.

How often do you judge your effectiveness by visible results rather than unseen obedience? Where have you dismissed a “failed” effort God might still redeem? Next time plans unravel, ask: Could this chaos be hiding someone’s salvation story?

“She said, ‘According to your words, so be it.’ Then she sent them away, and they departed. And she tied the scarlet cord in the window.”
(Joshua 2:21, ESV)

Prayer: Confess areas where you’ve prioritized productivity over people.
Challenge: Leave a Bible open to Joshua 2 where someone might “stumble upon” it today.

Day 3: Melting Hearts and Mountain Gods

Rahab gripped the spies’ cloaks. “Our hearts melted when we heard of your God drying seas and crushing kings. Everyone here knows—but I’m the only one acting.” Her trembling voice betrayed the cost: sheltering spies meant betraying her city. Yet she traded Canaan’s gods for the One who carves history like riverbeds. [32:05]

Acknowledging God’s power isn’t faith—Rahab proved that when her neighbors also trembled but didn’t repent. True belief wagers everything on divine character. Her scarlet cord wasn’t magic—it was the visible yes to the God who sees yeses in brothels.

What truth about God do you “know” but haven’t acted on? Where does your life look more like the paralyzed citizens than the treasonous believer? If your neighbors examined your choices this week, what god would they say you serve?

“The Lord your God is God in the heavens above and on the earth beneath.”
(Joshua 2:11, ESV)

Prayer: Thank God for specific moments He melted your resistance to His will.
Challenge: Share a “melted heart” moment—a time God overwhelmed you—with a coworker or neighbor.

Day 4: From Brothel to Bloodline

Rahab’s scarlet cord swung in the dawn light as Israel’s army marched. When walls fell, she gathered her family under that crimson banner. Years later, her son Boaz married Ruth the Moabitess. Their grandson Jesse fathered a king. Generations later, another scarlet-stained tree held her greatest descendant: Jesus. [38:57]

God wove a prostitute into Messiah’s lineage to show no one is beyond redemption’s reach. Rahab’s faith didn’t erase her past—it rewrote her future. The same blood that saved her house would save the world.

What labels from your past make you doubt God’s purpose? How might He be using your scars to point others to His redemption? If Jesus isn’t ashamed to call Rahab “mother,” what makes you think He’s ashamed of you?

“Salmon the father of Boaz, whose mother was Rahab, Boaz the father of Obed, whose mother was Ruth, Obed the father of Jesse.”
(Matthew 1:5, NIV)

Prayer: Ask God to reveal someone in your life who needs to hear Rahab’s story.
Challenge: Write a family tree of faith—people God used to bring you to Him.

Day 5: Unchanging Promise Keeper

Forty years earlier, ten spies saw giants. Joshua and Caleb saw God. Now, as new spies confirmed Jericho’s terror, Joshua remembered desert graves. But this time, the report ended differently: “The Lord has given us the land.” Same promise. Same God. No more doubting. [35:22]

God’s faithfulness outlives every failure. He waited forty years for Israel’s “hearts to melt” instead of their knees. His promises don’t expire—He fulfills them in His time, through His power.

Where are you still camping at the Jordan, paralyzed by past failures? What would change if you truly believed God’s timing isn’t procrastination but preparation? When has His delay revealed deeper mercy?

“God is not a man, that He should lie, nor a son of man, that He should change His mind. Does He speak and then not act? Does He promise and not fulfill?”
(Numbers 23:19, NIV)

Prayer: Name one long-unanswered prayer. Thank God He’s working even in the wait.
Challenge: Bake or buy bread today—a tangible reminder of God’s daily faithfulness.

Sermon Summary

A lively morning opens with community notes about quilting, youth group, workdays, and a pennies for principal drive, then moves into a personal story about a family debate over a pet that illustrates how promises function in everyday life. The narrative turns to the opening chapters of Joshua where a nation faces the long-awaited crossing into the promised land. Joshua orders the people to prepare, and he reminds the two and a half tribes of the promise they made to Moses to assist their countrymen in battle. Those tribes renew their vow and agree to lead the way, restoring national unity and enabling the move toward the land God promised to Abraham generations earlier.

Joshua then sends two spies secretly into Jericho. Their covert mission leads them to Rahab, a woman on the margins who hides the spies, lies to the city authorities, and confesses a bold faith in the God of Israel. Rahab bargains for the safety of her family and secures a promise from the spies, trusting an oath she has no proof will be kept. The spies return with news that confirms fear among the Canaanites and reaffirms God’s promise, yet tactically the scouting yields no military advantage. The real outcome is relational and redemptive: Rahab and her household are spared and welcomed into Israel’s story; her lineage later links to David and ultimately to Jesus.

The narrative frames violence and judgment within God’s long covenant faithfulness and highlights an unexpected mercy. God’s prior declarations of judgment do not exclude a present willingness to rescue a repentant outsider. Scripture then calls readers to wrestle with the essential question of trust. The cumulative witness of Moses, Joshua, Rahab, and later scripture insists that God does not lie and does not change. The congregation is invited to move from intellectual assent to a lived confidence in God’s fidelity, offering testimonies of God’s steady provision and asking for help in moments of doubt. The conclusion emphasizes that the book of Joshua, beyond its human characters and battles, showcases the unerring faithfulness of God who seeks the lost and fulfills covenant promises.

Key Takeaways

1. God keeps his covenant promises God’s actions across generations reveal a consistent character that honors covenant commitments. The promise first given to Abraham moves forward through Moses and Joshua and finds unexpected fulfillment even in the inclusion of outsiders. Trusting God means anchoring life decisions in a history of divine fidelity rather than immediate circumstances. [42:22]
2. Faith often requires risky trust Rahab’s choice to protect the spies placed her at odds with her community and under threat of death. Real faith sometimes looks like treason to the world because it risks safety for allegiance to God’s revealed truth. Such risks do not rest on impulse but on informed hope in God’s faithful character. [33:02]
3. God pursues the lost intentionally Sending spies led not to tactical gain but to the rescue of one who turned toward God. The narrative shows God’s priority to bring outsiders into the covenant community, making mercy part of the conquest story. This frames salvation as relational and purposefully sought, not incidental. [36:31]
4. Promises shape communal responsibility The two and a half tribes kept a vow that bound them to assist their neighbors despite enjoying their own land. Vows matter because they hold communities together and enable collective movement toward God’s purposes. Faithful communities require mutual accountability to the promises that sustain them. [22:31]

Bible Reading
Joshua 2:1-14 (ESV)
1 And Joshua the son of Nun sent two men secretly from Shittim as spies, saying, “Go, view the land, especially Jericho.” And they went and came into the house of a prostitute whose name was Rahab and lodged there. 2 And it was told to the king of Jericho, “Behold, men of Israel have come here tonight to search out the land.” 3 Then the king of Jericho sent to Rahab, saying, “Bring out the men who have come to you, who entered your house, for they have come to search out all the land.” 4 But the woman had taken the two men and hidden them. And she said, “True, the men came to me, but I did not know where they were from. 5 And when the gate was about to be closed at dark, the men went out. I do not know where the men went. Pursue them quickly, for you will overtake them.” 6 But she had brought them up to the roof and hid them with the stalks of flax that she had laid in order on the roof. 7 So the men pursued after them on the way to the Jordan as far as the fords. And the gate was shut as soon as the pursuers had gone out. 8 Before the men lay down, she came up to them on the roof 9 and said to the men, “I know that the Lord has given you the land, and that the fear of you has fallen upon us, and that all the inhabitants of the land melt away before you. 10 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, to Sihon and Og, whom you devoted to destruction. 11 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. 12 Now then, please 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 13 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.” 14 And the men said to her, “Our life for yours even to death! If you do not tell this business of ours, then when the Lord gives us the land we will deal kindly and faithfully with you.”

Numbers 23:19 (ESV)
God is not man, that he should lie, or a son of man, that he should change his mind. Has he said, and will he not do it? Or has he spoken, and will he not fulfill it?

Deuteronomy 7:9 (ESV)
Know therefore that the Lord your God is God, the faithful God who keeps covenant and steadfast love with those who love him and keep his commandments, to a thousand generations.

#TrustGodsWord

“Can you trust God at his word? Do you believe that what God has said is true? Because ultimately, everything in our lives hinges on this. Do I believe God is faithful? Do I believe God at his word? God invites us to know him, to find forgiveness and mercy in him, to to receive salvation through him. Whether God is faithful, whether God keeps his word is essential to who we are. Can I trust God? Do I believe that he is faithful?”

#GodNeverChanges

“James reminds us again, God does not change. God does not shift like the shadows. He remains constant and fixed in his word and in his invitation. God was the one who has chosen to give us life. Do we trust him? Do we believe him? Rahab staked her future on who God is as a faithful, oath keeping God. And ultimately, each one of us have to make that same choice. Will we trust God at his word? Do we believe that God is faithful? No. How do we know? Kind of the follow-up question is, I wanna believe God is faithful, how do I ultimately know? At some point, it takes a step of faith.”

#FaithfulGodInJoshua

“You see, we've spent the last two weeks looking at who Joshua is and and where he finds his identity. Today, as we start his book, we quickly realize how little the book of Joshua is about Joshua. It's it's not even really about the promises and the actions of the specific characters we're reading about this morning. Instead, we find that this book is ultimately just one more example of the unerring faithfulness of God. A God who promises to never leave us or forsake us. A God who promises to remove our sins as far as East is from the West. A God who invites us into his kingdom through the gift of his son, Jesus.”

#MosesProclaimsFaith

“Moses is facing his own death. Moses is facing the consequences of his sin. Remember, for forty years, he's been leading the nation towards the land of promise, and God has just told him a year earlier, you don't get to go in. You don't get to go see the land of promise. Stay on the mountain, you can look at it, but you don't get to go in. Moses proclaims the goodness and the faithfulness of God. Even though he's facing consequences, even though he's about to die, everything else in his life kind of fades in comparison saying, this is who God is. God is faithful. God fulfills his word.”
