Week 28: Crossing the Jordan

Overview

Moses is dead. The greatest figure in Israel’s history lies in an unmarked grave on the wrong side of the Jordan, buried by God himself, mourned for thirty days. And now God speaks to Joshua — and his first word is not comfort but command: “Moses my servant is dead. Now therefore arise, go over this Jordan, you and all this people, into the land that I am giving to them” (Joshua 1:2). The time for mourning is over. The promise that has been traveling since Genesis 12 — “To your offspring I will give this land” — is about to be kept.

The charge God gives Joshua is saturated with repetition that is itself a revelation: “Be strong and courageous” (Joshua 1:6). “Only be strong and very courageous” (Joshua 1:7). “Have I not commanded you? Be strong and courageous. Do not be frightened, and do not be dismayed, for the LORD your God is with you wherever you go” (Joshua 1:9). Three times. The repetition is not rhetorical filler. It is medicine for a man who has just watched his mentor die without entering the promise. Courage is not the absence of fear. It is obedience in the presence of fear — sustained by a God who goes ahead.

Before the crossing, the narrative pauses for Rahab. A Canaanite prostitute living in the wall of Jericho hides the Israelite spies on her roof, under stalks of flax. She confesses faith in a God she has only heard about: “The LORD your God, he is God in the heavens above and on the earth beneath” (Joshua 2:11). Her theology is better than the ten spies’ at Kadesh-barnea. She has heard what God did at the Red Sea, and she believes it. The scarlet cord she hangs from her window — the sign that will save her family when Jericho falls — is a thread of faith woven through the wall of a condemned city. She is a Canaanite. She is a prostitute. She is the most unlikely convert in the narrative. And she will enter the genealogy of the Messiah.

The Jordan crossing deliberately echoes the Red Sea. The priests carry the ark into the river at flood stage — “the Jordan overflows all its banks throughout the time of harvest” (Joshua 3:15). The moment their feet touch the water, the river stops flowing. Israel crosses on dry ground. Twelve stones are taken from the riverbed and stacked on the western bank as a memorial, “that all the peoples of the earth may know that the hand of the LORD is mighty” (Joshua 4:24). The God who divided the sea for the first generation divides the river for the second. His faithfulness does not expire with the people who doubt it.

Jericho falls — not to military strategy but to liturgical obedience. Seven days of marching. Seven priests carrying seven trumpets. On the seventh day, seven circuits around the city. Then a shout. And the walls collapse. The first victory in the Promised Land is won not by siege engines or tactical genius but by doing exactly what God said, even when what God said sounded absurd. The foolishness of the strategy is the point. The victory belongs to God, and the method ensures everyone knows it.

But immediately after Jericho comes Ai — and defeat. Achan has taken devoted things from Jericho’s ruins: a beautiful cloak from Shinar, two hundred shekels of silver, a bar of gold. He buried them under his tent. No one saw. But God saw. Israel is routed at Ai, thirty-six men die, and God tells Joshua the reason: “Israel has sinned; they have transgressed my covenant” (Joshua 7:11). One man’s hidden disobedience brings public defeat on the entire community. The covenant binds them together — for blessing and for curse. Achan is identified, confesses, and is executed with his family in the Valley of Achor (trouble). The juxtaposition with Jericho is deliberate and devastating: obedience topples walls; disobedience, even when hidden, opens the camp to destruction.

The southern and northern campaigns follow (Joshua 9-12), summarized with sweeping brevity: city after city falls, king after king is defeated. Joshua 12 lists thirty-one conquered kings — a ledger of divine promise kept by divine power. The land is being taken. Not completely — much remains. But the momentum is unmistakable. God is doing what he said he would do.

This Week’s Readings

Key Themes

• The Jordan as new beginning — The crossing echoes the Red Sea with unmistakable deliberation: water divided, dry ground, a nation walking through on foot. But this is not escape. It is arrival. The generation born in the wilderness now stands on the soil of the promise. The memorial stones are set so that children will ask, “What do these stones mean?” (Joshua 4:6). The answer is always the same: God keeps his word.
• Victory by obedience — Jericho falls not by siege but by marching, trumpets, and a shout. The method is absurd by every military calculation. That is the point. God’s methods do not need to make sense to us. They need to be obeyed. The first conquest in the Promised Land establishes the principle that will govern the rest: obedience is the mechanism of victory.
• Rahab — A pagan prostitute in a condemned city confesses faith in the God of Israel and is spared. She believed what Israel’s own spies at Kadesh-barnea refused to believe. Her inclusion shatters every assumption about who belongs in the covenant. The scarlet cord in her window is faith made visible, hanging from the wall of a city about to fall.
• Hidden sin and communal consequence — Achan’s private disobedience leads to public defeat. One man’s sin affects the entire community. The covenant is corporate — its blessings shared and its curses shared. There is no such thing as private sin in a covenant community. What is buried under one tent undermines every tent in the camp.

Christ in This Week

Joshua’s name is itself a sermon. Yehoshua — “the LORD saves.” It is the same name that will be given to a baby in Bethlehem: “You shall call his name Jesus, for he will save his people from their sins” (Matthew 1:21). The Greek Iesous translates the Hebrew Yehoshua. The one who leads Israel into the Promised Land carries the same name as the one who leads God’s people into eternal rest. The author of Hebrews makes the connection explicit and then transcends it: “For if Joshua had given them rest, God would not have spoken of another day later on” (Hebrews 4:8). Joshua brought them into the land. He could not bring them into rest. That awaits a greater Joshua — one whose victory is not over Canaanite kings but over death itself.

Rahab — the Canaanite prostitute saved by faith — appears in three New Testament lists, and each one makes a different argument. Matthew places her in the genealogy of Christ (Matthew 1:5), declaring that the Messiah’s bloodline includes a pagan woman from a condemned city. Hebrews lists her among the heroes of faith: “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). James cites her as evidence that faith without works is dead (James 2:25). She believed, and she acted. She is the gospel in miniature before the gospel has a name: a sinner, an outsider, who hears about God’s power, believes it, acts on it, and is incorporated into the people of God — and into the lineage of the King.

And Jericho — the fortified city brought down not by military power but by obedient worship — previews the way Christ conquers. Not by the sword. Not by political force. Not by the methods the world respects. “For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds” (2 Corinthians 10:4). The walls of Jericho fell to trumpet blasts and a shout. The power of sin and death falls to a cross and an empty tomb. The strategy looks foolish. “For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God” (1 Corinthians 1:18). God’s method of conquest has always been the same: victory through what the world considers defeat.
