📖 Old Testament Survey — Unit 4: Conquest and Chaos (Joshua, Judges, Ruth)

Three Books, Three Verses, Three Eras

Joshua 1:9 — "Be strong and courageous." Judges 21:25 — "Everyone did what was right in his own eyes." Ruth 1:16 — "Where you go, I will go." Three sentences. Three eras. And every reader has to ask: which of these three sentences am I living by this week?

I. Joshua — Be Strong and Courageous

Joshua picks up where Deuteronomy stopped. Moses is buried. The cloud is still moving. And the LORD says to a man who has been Moses' assistant for forty years, "Moses my servant is dead. Now therefore arise, go over this Jordan" (Joshua 1:2). The God of Israel does not bury His purposes when He buries His servants.

Notice the name. Yeshua — "the LORD is salvation." It is the same name an angel will tell a young carpenter to give a baby fifteen hundred years later. The first Joshua led a people to the land. The Greater Joshua leads them home.

A single woman of thirty‑six once came to her pastor and said, "I want to get in on God's plan for my life." She wasn't sure that plan included a husband, but she wanted in either way. That sentence is the whole spirit of Joshua. The wilderness generation had died refusing to trust God's plan. The new generation faced the same plan, the same God, the same promise — and said yes. Joshua's whole book is the question put to that woman, and to every reader: are you in on God's plan, or are you still standing on the wrong side of the river?

A. Crossing the Jordan

The first miracle of Joshua's leadership is Jordan at flood stage. The priests carrying the ark step into the water — and only when their feet are in does the river stop. God did not part the Jordan a hundred yards upstream so Israel could walk down dry. He waited until obedient feet got wet. That is how God deals with His people more often than not. The instruction is "step in." The water stops once the feet are wet.

Then the ark is carried into the middle of the riverbed, and the whole nation walks across with the ark in plain sight on dry ground. The seat of God's presence stands in the place where death would have come, and the people pass through safely on its account. A fifteen‑century‑later picture of a cross in a dry valley. We go through Jordan only because Christ stood in the water for us.

Joshua then sets up two piles of stones. One pile is on the shore at Gilgal — twelve stones, one from each tribe, for the people to see for generations and tell their children, "These stones mean the LORD held the Jordan back for us" (Joshua 4:6–7). And then a second pile — a stack of twelve stones in the middle of the riverbed itself, exactly where the priests had stood with the ark (Joshua 4:9). When the waters returned, those stones were covered. They lie there still, under the river. No man has seen them since. They were not built for human eyes. They were built for God. There are some altars the LORD asks you to build that nobody else will ever know about. He sees. He remembers. Centuries later the Greater Joshua would give His people one more memorial — not stones in a river, but bread and a cup at a table — and tell them, "Do this in remembrance of Me".

B. The Commander of the LORD's Army

Before Jericho falls, Joshua is alone outside the city, looking up at its walls. Suddenly a Man stands in front of him with a drawn sword in His hand. Joshua, the seasoned general, asks the obvious question: "Are You for us or for our adversaries?" And the Man gives an answer that nobody saw coming. "No" — neither side — "but as Commander of the army of the LORD I have now come" (Joshua 5:13–14). Joshua falls on his face. The Commander says, "Take your sandal off your foot, for the place where you stand is holy" — the same words once spoken from a burning bush. This is no ordinary angel. This is the pre‑incarnate Christ standing with a drawn sword on the eve of the conquest. The God of Israel does not finally take sides in our battles. He commands them. Before you can do any great work for God, you must first meet God face to face.

C. Rahab and the Scarlet Cord

Inside the doomed city, two spies are hidden by a Canaanite prostitute named Rahab. Her negotiation contains the most surprising sentence in the chapter: "I know that the LORD has given you the land" (Joshua 2:9). Rahab — pagan, immoral, marked for destruction — has more theology than half of Israel. She bargains for her family's lives and is told to hang a scarlet cord from her window so that the army will know which house to spare.

A scarlet cord. In a window. The army of God passes by every house that has the scarlet cord and judges every house that does not. Read that sentence again. The Bible has been telling that story since the Passover — and behind the Passover, since Moriah, and behind Moriah, since Eden. We have arrived at the next great station on the Scarlet Thread. The same blood that covered Adam and Eve, that flowed from Abel's altar, that flowed from Noah's altar, that spared a ram on Moriah, that brushed the doorposts of Egypt, that was sprinkled on the mercy seat in Leviticus, that flowed from a bronze serpent in Numbers — that same line of innocent blood is now a single cord in the window of a brothel in Jericho. And what makes it more astonishing is that Matthew opens his Gospel listing Rahab in the genealogy of Jesus (Matthew 1:5). The Moabitess Ruth and the murderer‑king David and Rahab the prostitute all stand in the line that produces the Savior. Grace keeps reaching for the people the religious world wrote off.

D. Jericho — and Achan

Jericho is the first miracle of obedience in the new land, and it is the strangest battle plan ever issued. March around the city for six days. On the seventh day, march seven times, then shout. The walls fall. There is not a sword raised by an Israelite hand. Most Christians have their own Jericho. It is the wall they keep marching past instead of around. They have been told to march and shout, and they want to climb. So the wall stays up.

Then Achan. One man hides a robe and some silver under his tent — a few square feet of forbidden goods — and the next battle Israel fights, at little Ai, ends with Israelite men dead in the field. Achan thought his sin was private. There is no such thing in the camp of God. Hunters in some places trap monkeys with a hollowed gourd full of nuts and a hole just big enough for a monkey's open hand to slip through. The monkey grabs the nuts. He cannot pull a closed fist back out. All he has to do to be free is let go — and he will not. Achan would not let go of his robe and his silver. Many believers grip their nuts and call themselves trapped. The camp is your home. The camp is your church. What you have buried under your tent affects the people standing next to you. That is not a guilt trip. It is the way a holy God deals with His people.

E. Cities of Refuge

Before his death, Moses had commanded that six cities, scattered across the land, be set apart as cities of refuge; now Joshua carries out the plan and appoints them (Joshua 20). If a man killed another by accident — the head of an axe slipping off a handle, a stone falling from a wall — the avenger of blood from the victim's family would be after him. He could flee to the nearest city of refuge and live there safely until his case was heard. The roads to those cities were graded and marked. Bridges were kept in repair. Signposts pointed the way. The Lord did not want a man stumbling toward the safe house in the dark.

Years ago a woman fled an abusive husband and was hidden in a church‑run safe house several hours from her home. She had children with her. She had a new identity. He could not find her — not because she was hiding well, but because someone had built a place for her to be safe. She joined a small church and began to breathe again. That is what the cities of refuge are. Christ is the refuge. The roads to Him have been graded. The signposts are everywhere in Scripture. The Father has built the safe house, and not one of His pursued people will fail to make it to the gate if they will run.

F. Joshua's Farewell

Joshua lives long enough to give one of the great deathbed speeches of the Old Testament: "Choose this day whom you will serve... but as for me and my house, we will serve the LORD" (Joshua 24:15).

I knew of a dying deacon named Bob Key who shared a hospital room with a man named Tom who had no use for the gospel. For days Bob preached Christ to Tom in pieces — between treatments, between pain. The morning Bob died, Tom got up out of his hospital bed, walked over to where Bob was lying, and gave his life to Christ at the bedside of the dying man who had refused to stop preaching to him. That is "as for me and my house" lived to the last hour. Joshua spent his life serving the LORD. He spent his death calling other people to do the same.

II. Judges — Everyone Did What Was Right in His Own Eyes

After Joshua dies, the elders he trained outlive him for a generation, and then the wheels come off. Judges covers about three hundred and fifty years of slow national decay. The structure is a wheel that keeps turning: Israel sins, God allows oppression by a neighbor, Israel cries out, God raises a deliverer (a judge), Israel knows peace until the judge dies — and then the wheel turns again. Same wheel. Same sins. Same misery. The book ends on the verse that names the whole era: "In those days there was no king in Israel; everyone did what was right in his own eyes" (Judges 21:25).

Hear that as it was meant. It is not a compliment of independence. It is a coroner's report on a society. When everyone in a culture is the final arbiter of right and wrong, the culture is dying. Judges shows you how that death looks in slow motion.

A. Three Judges

Deborah — a prophetess who rises when no man will. She summons Barak to lead the army and he refuses to go without her. Deborah goes. The Canaanite general Sisera dies of a tent peg through the temple, driven by a woman named Jael. When the men will not lead, the LORD will use whomever stands up.

Gideon — the man God called from threshing wheat in a winepress because he was afraid of the Midianites. The famous detail is the army. Twenty‑two thousand men show up. God says too many. Send the fearful home. Ten thousand left. God says still too many. Watch them drink. Three hundred. With three hundred men and three hundred clay jars and three hundred trumpets, Gideon defeats an army the Bible says was as numerous as locusts on the plain. The point is exact: God shrinks armies until His people cannot mistake who won.

Samson — a man set apart from the womb, gifted with strength no man could match, and undone by women he should never have looked at twice. Samson could break a lion. He could not break a habit. The strongest man in the Old Testament is left blind and in chains, grinding grain in a Philistine prison — and even his last act of faith, pulling Dagon's temple down on himself, was only possible because the LORD was merciful enough to come back when Samson finally cried out. There is hope in Samson's last prayer. There is also a warning. Gifting is not godliness. A man can preach in chains he forged for himself.

B. The Cycle Is Yours

Pause and apply the cycle. It is not in a museum. It is on your phone. You sin. Things get hard. You cry out. God shows mercy. You feel relief. You forget. Repeat. The reason Israel could not break the cycle is the reason most believers cannot break it either: the cycle does not break until a King takes the throne the heart was built to seat. Judges ends crying out for a king. Judges ends pointing forward to Christ.

III. Ruth — Where You Go, I Will Go

In the middle of the chaos, the LORD writes a love story.

Ruth opens "in the days when the judges ruled" — same era, same decay. The names in this little book tell their own story before the action even begins. Elimelech means my God is King. Naomi means pleasant. Their two sons are Mahlon — sick — and Chilion — pining away. A famine drives the family across the Jordan into Moab. Within a decade Elimelech has died, both sons have died, and Naomi is left with two Moabite daughters‑in‑law and not a male relative on the planet. She tries to send them home. One goes. The other says the line that has been quoted at every wedding for three thousand years: "Where you go, I will go; and where you lodge, I will lodge. Your people shall be my people, and your God my God" (Ruth 1:16). Ruth means beauty. The beauty in this book is hers.

Naomi comes home to Bethlehem with bitter lips. "Do not call me Naomi — call me Mara, for the Almighty has dealt very bitterly with me" (Ruth 1:20). Pleasant has become bitter. And yet behind the bitterness, God has been preparing a redemption Naomi cannot yet see.

Notice what Ruth is choosing when she clings to her mother‑in‑law. She is not choosing romance. There is no Boaz yet. She is not choosing comfort. She is choosing a widow with empty hands and a God she has only recently met, over the only world she has ever known. That is what conversion looks like. Conversion is not a feeling. It is a decision to stand with God's people through famine.

A. Boaz the Kinsman‑Redeemer

Ruth goes out to glean and the Bible says she "happened" to come to the field of a man named Boaz (Ruth 2:3). Whenever you see the word "happened" in the Old Testament, write the word providence in the margin. There are no accidents in a book God is writing. The same hand that led a small fish to swallow a coin Peter would later use to pay the temple tax led a young Moabitess to glean in the field of a near relative of her dead father‑in‑law.

The name Boaz means strength. He is a near relative of Naomi's husband, and Hebrew law made provision for a near relative — a go'el, a kinsman‑redeemer — to step in when a family was in crisis: to buy back land that had been sold off, to take a widow as wife, to keep the family name alive. The catch was that the go'el had to be near, willing, and able. Many men can be near. Some are willing. Few are also able.

Boaz is all three. And that is why Boaz is one of the clearest pictures of Christ in the Old Testament. Christ is our kinsman — He took on flesh to be near us. Christ is willing — He came of His own choice. Christ is able — He had the price to pay, and He paid it. The whole gospel sits inside the legal vocabulary of Ruth chapter four.

B. The Scarlet Thread Runs On

The book ends with a genealogy that should stop the reader cold. Ruth bears a son. His name is Obed — worship. Obed becomes the father of Jesse. Jesse becomes the father of David. The Moabite outsider in the time of the judges is the great‑grandmother of the king of Israel — and an ancestor of Jesus of Nazareth. The same scarlet thread that hung in Rahab's window in Joshua 2 runs straight through Ruth 4 to Bethlehem to a manger.

That is how God writes a story. While Judges is producing chaos on the front page, Ruth is producing the Messiah on the back page. The work of grace runs underneath the news.

IV. Christ in Conquest and Chaos

Christ is the true Joshua — the Commander of the LORD's army who appeared with sword drawn at Joshua 5, the Greater Yeshua who leads His people into rest (Hebrews 4). Christ is the King the Judges era cried out for — the only one who can finally end the cycle of sin and self‑rule. Christ is the Kinsman‑Redeemer Ruth needed — near, willing, and able to redeem at His own cost. Christ is the refuge to whom every road has been graded for the pursued sinner who will run.

Three convictions to take from these three books. First, God's redemption runs underneath the news. Joshua looked like a war. Judges looked like a collapse. Ruth looked like a widow in a barley field. From outside, the work of God in any of these three eras was almost invisible. But looking back you can see the scarlet thread. He does that in your story too. The day you cannot trace His hand, trust His thread. Second, the verse you live by becomes the era you create. "Be strong and courageous" produces Joshua. "Everyone did what was right in his own eyes" produces Judges. "Where you go, I will go" produces Ruth. Most homes, most churches, most marriages live by one of those three sentences. Choose carefully. Third, Christ keeps grafting outsiders in. Rahab the prostitute. Ruth the Moabitess. Both stand in the line of Jesus. Grace has been reaching for the people the religious world wrote off since the gates of Jericho.
