Joshua 1-2: Be Strong and Courageous! And Rahab's Scarlet Thread

About This Episode

Joshua begins with the command to be strong and courageous and the promise that God will be with Israel as the go to battle. The first city on Israel's battle plan is Jericho. But in Jericho a prostitute named Rahab pledges allegiance to Yahweh. Seth and David talk about the significance of Rahab's story at the beginning of a book full of military battles, and why being strong and courageous is a metaphor for faith in Jesus.

Joshua 1–2: God's Presence, Strength and Courage, and Rahab's Surprising Faith

Show Notes

David Bowden and Seth Stewart, co-hosts of the Spoken Gospel podcast, open this episode by diving into the first two chapters of Joshua. Having covered the overview of Joshua in a previous episode, they turn their attention to two of the most well-known moments in the book: the famous command to "be strong and courageous" and the story of Rahab the prostitute hiding the Israelite spies. What emerges across the episode is a rich, layered reading that connects these chapters back to the Garden of Eden, forward to Jesus, and deep into the heart of what it means to live by trust in God's presence.

The Land as Gift and the Echoes of Eden

The episode begins by setting Joshua 1–2 within the larger structure of the book. The first 12 chapters of Joshua focus on the conquest of the land, while the second half deals with the tribal allotments. But before any battle occurs, the text frames the conquest in theological terms rather than militaristic ones. The land of Canaan is described as a gift from God (Joshua 1:2), not a prize seized by Israelite ambition. God's faithfulness to His promises—stretching all the way back to Abraham—is what drives the narrative.

Two key themes from Genesis surface immediately. First, the language of Joshua's foot treading on the land echoes Genesis 3:15, where God promised that the descendant of Eve would crush the head of the serpent. Joshua, as a representative of Eve's line, is stepping into a land inhabited by the seed of the serpent—the Canaanites and even the Nephilim—and treading upon them. This is not mere territorial expansion; it is a theological act of reclaiming creation from the forces of the curse. Second, the command to subdue the land and fill it mirrors Genesis 1:28, where God told Adam and Eve to fill the Earth and exercise dominion over it. Joshua's mission is a continuation of that original vocation: to bring God's order, presence, and blessing into a world overrun by rebellion and corruption.

The analogy of a gardener reclaiming a once-beautiful garden gone to ruin captures the heart of what is happening. Joshua enters Canaan to pull out the weeds of wickedness and restore the land to its intended purpose—a place where God dwells with His people. And all of this points to Jesus, who fulfills what Adam, Eve, and Joshua could only partially accomplish. Scripture tells us that all things are placed under Jesus's feet (Ephesians 1:22), that His Kingdom fills the whole Earth, and that He subdued even the realm of Death by entering it and conquering it. What Joshua attempted in the land of Canaan, Jesus accomplishes over the entire world, not by creating a "Garden 2.0" but by finishing the work that was always intended from the beginning.

Be Strong and Courageous: Trust Rooted in God's Presence

One of the most frequently quoted phrases in all of Scripture—"Be strong and courageous"—appears three times in Joshua 1, alongside four assurances that God will be with His people. The episode challenges a common misreading of this command. It is not a call to muster personal bravery against a hostile culture; it is a call to trust in the reality of God's presence. The strength and courage Joshua needs are rooted not in the size of the enemy but in the faithfulness of his ally.

When God says, "Just as I was with Moses, so I will be with you. I will not leave you or forsake you" (Joshua 1:5), He is essentially repeating the divine name He gave to Moses at the burning bush. "I will be with you" is the same declaration as "I am"—Ehye in Hebrew. God is telling Joshua that the same presence that parted the Red Sea and sustained Israel through the wilderness will now go with him into battle. Without that presence, there is no victory, no rest, no garden. The book of Judges, which follows Joshua, vividly illustrates what happens when a people have the land but lack the presence of God—the result is chaos.

This has profound implications for the life of anyone who follows Jesus. God's presence is not a warm feeling experienced during worship, though it can include that. It is creative, sustaining, and world-altering. As Paul writes, all things exist by Him, through Him, and for Him (Romans 11:36). Without God's presence, everything falls apart. With it, rest, victory, and true flourishing become possible. The promise extends directly into the New Testament, where Jesus tells His disciples, "I am with you always, even to the end of the age" (Matthew 28:20), a promise fulfilled through the indwelling Holy Spirit. When Paul asks, "If God is for us, who can be against us?" (Romans 8:31), he is drawing on the same logic that anchors Joshua 1: courage flows from the knowledge that God is present with His people.

Obeying God's Law as an Act of Courage

An often-overlooked dimension of "be strong and courageous" is its direct connection to obeying the Torah. The text does not merely tell Joshua to be bold in battle; it tells him to be careful to obey all the law, not turning from it to the right or to the left, meditating on it day and night (Joshua 1:7–8). This equation—strength and courage equals faithful obedience to God's word—reframes how we think about the Christian life.

The laws of God are extensions of His presence and character. When the law says "do not murder," it is embedding the God of life into the fabric of a community. To disobey the law is to push against the very presence of God that makes flourishing possible. But God's commands inevitably cut across the grain of every culture. They demand sacrifice. They challenge our preferred ways of finding justice, sexual satisfaction, financial security, and social belonging. Obeying them requires genuine bravery—the courage to remain single and celibate when the culture insists on sexual fulfillment, to be radically generous when financial security seems paramount, to tell the truth when a lie would be easier.

This is ultimately what the new covenant promises. God does not simply hand down laws and demand compliance. Through the Holy Spirit, He transforms His people into those who have the strength and courage to obey from the inside out—an idea previewed in Ezekiel's prophecy and realized in the life of every person who trusts Jesus. God is with us so that we might actually become the kind of people who can live in His Kingdom.

Rahab: The First Conquest Is a Victory of Grace

Joshua 2 introduces one of the Bible's most remarkable stories: Rahab the prostitute harboring the Israelite spies. Before any military campaign, before any wall falls, the first "conquest" in the promised land is a conquest of a Canaanite woman's heart. She is a prostitute, a Canaanite, and a woman—three categories that would place her at the absolute margins of Israelite society. And yet she becomes the first person in the promised land to confess faith in Yahweh.

The episode draws attention to a deliberate echo of Numbers 13. When Moses first sent spies into Canaan, 12 went, and only two—Joshua and Caleb—returned with a good report. This time, Joshua sends only two spies, and both return with good news. It is a subtle, almost humorous narrative correction: Joshua learned from the previous failure.

Rahab's confession is theologically stunning. In a polytheistic culture where every city had its own territorial god, she declares, "Yahweh your God, He is God in the heavens above and on the earth beneath" (Joshua 2:11). She is obeying the first commandment. She is rejecting the gods of Canaan and placing her trust in the God who parted the Red Sea and defeated the kings of the Amorites. While the rest of Jericho heard about Yahweh's power and hardened their hearts in resistance, Rahab heard the same news and let her heart melt in worship. The text presents these as the only two responses to the advancing Kingdom of God: resist or surrender.

Hesed, Herem, and the Scarlet Cord as a New Passover

Two critically important Hebrew words surface in Joshua 2. The first is hesed—covenant loyalty, steadfast love—which Rahab uses when she asks the spies to deal "kindly" with her family as she has dealt kindly with them (Joshua 2:12). She is essentially asking to be brought into the covenant community on the basis of the same faithful love that God shows His people. This is remarkable because hesed is a word normally reserved for God's relationship with Israel, and here it is spoken by a Canaanite prostitute. Rahab's story ripples through the rest of Scripture: she becomes the mother of Boaz, whose own hesed love for Ruth—another foreigner—is celebrated in the book that bears her name. And through that line, Rahab becomes one of the foremothers of Jesus (Matthew 1:5).

The second word is herem—devoted to destruction, the holy ban of God. The first time this word appears in Joshua, it is on Rahab's lips as she describes the destruction of Sihon and Og (Joshua 2:10). The fact that the word for total destruction is first spoken by someone who is about to be saved from it is deeply significant. It tempers every subsequent use of the word throughout the book. Grace precedes judgment.

The arrangement the spies make with Rahab—hanging a scarlet cord from her window so that her household will be spared—functions as a new Passover. Just as the Israelites in Egypt painted their doorposts with the blood of the lamb and remained inside their houses while the angel of Death passed over, Rahab and her family are to stay inside her house marked with the scarlet cord while the destruction of Jericho passes over them. But this time, the Passover is not for Israel. It is for a Canaanite family. This signals that God's saving work extends beyond Israel to the nations, that there is a remnant even within the enemy's camp whom God is rescuing.

Digging Deeper Than the Scarlet Thread

The episode closes with a candid conversation about how the story of Rahab is often preached. The "scarlet thread" through Scripture—a line from Genesis 3:15 through to Jesus, symbolized by the red cord—is a popular and not entirely wrong framework. But the concern is that treating the cord's color as the main connection to Jesus is a shortcut that bypasses the richer, deeper theology at work. The point of the passage is not the color of the cord. It is the Passover pattern of God's judgment passing over those who take shelter under His protection. It is the interplay of hesed and herem, grace and destruction. It is the stunning reality that God invites even a Canaanite prostitute into His covenant people and then uses her family line to bring the Messiah into the world.

Details in Scripture can be significant—the purple robes draped on Jesus signal royalty, the pomegranates etched into the tabernacle recall the garden—and the scarlet cord may well carry symbolic weight. But the call is to do the work of understanding why these details matter within their larger story rather than leaping to a surface-level gospel connection and stopping there. There is always better news the deeper you look.
