The Troubler Of Israel: When Secret Sin Leads To Public Defeat
Contributed by Paul Dayao on Sep 13, 2025 (message contributor)
Summary: This sermon from the sobering account of Achan in Joshua 7 exposes how one person's secret sin can cause corporate spiritual defeat, charting the painful but necessary path from the Valley of Trouble to the door of hope.
Introduction: The Anatomy of a Defeat
Imagine the spirit in the camp of Israel. They are standing on the smoking ruins of Jericho, a city whose walls were built to defy armies. They have not just won a battle; they have witnessed a miracle. They are God's chosen people, marching under His banner, filled with an intoxicating sense of destiny and power. Victory is in the air. Their hearts are invincible.
The next objective is a small town named Ai. The name literally means "a heap of ruins." In their confidence, the spies return with an almost arrogant report: "They are but few." This will be nothing.
But the unthinkable happens. The mighty army of Israel, the conquerors of Jericho, are routed by the soldiers of a backwater town. They are chased down the hillsides like frightened sheep. Thirty-six of their brothers, who just days before had marched in triumph, now lie dead on the battlefield. And the Word of God gives us this devastating report: "...the hearts of the people melted, and became as water." In a single moment, their supernatural courage vanished, replaced by a flood of fear and shame.
Their leader, Joshua, is shattered. He tears his clothes, falls on his face, and cries out to God with the question that frames our entire message today: Why? Why has victory been swallowed by defeat? Why has our strength turned to weakness? Why has our confident advance become a humiliating retreat?
This chapter is a spiritual autopsy report. It is the anatomy of a defeat. And God calls us to examine it closely, for it contains a solemn and timeless warning about a danger that can cripple any church, any family, and any believer today.
I. The Cause of Defeat: A Secret Sin (v. 1, 10-12)
God's answer to Joshua's desperate prayer is not a comforting whisper; it is a lightning bolt of truth. He says, "Get thee up; wherefore liest thou thus upon thy face? Israel hath sinned..." The problem was not a failure in God's power. The problem was a poison in God's people.
The Trespass: The core of the sin was a violation of the "accursed thing," or herem. God's command for Jericho was absolute. As the first city conquered, it was the "firstfruits" of the land, belonging entirely to Him. Every living thing was to be destroyed, and all the treasure was to be consecrated to the Lord's treasury. This was not about looting; it was an act of worship, declaring that God alone is the conqueror and to Him belongs the glory. But Achan "committed a trespass." He saw what belonged to God and decided it should belong to him. His sin was not merely theft; it was sacrilege. He robbed God directly.
The Deception: Notice the progression of the sin. Achan took the forbidden items, and then, as verse eleven says, he "dissembled also, and... put it even among their own stuff." He lied through his silence. He went back to his tent, dug a hole in the dirt floor of his private space, and buried his sin under a cloak of secrecy. The tent is a powerful picture of our private lives—that hidden space in our hearts, our homes, our internet history. Achan thought what he did in the secrecy of his tent was his own business. He was tragically mistaken.
The Corporate Consequence: The most terrifying phrase in this story is God's declaration: "Israel hath sinned." One man's "private" sin became the entire nation's public disgrace and defeat. God held the entire community responsible. This is the principle of corporate solidarity. Sin is like a virus. One person's secret infection, if left undealt with, will inevitably sicken the entire body. Your secret sin is never truly secret. It releases a poison of spiritual weakness into your family and your church, making everyone more vulnerable to attack and defeat.
II. The Character of Defeat: A Melted Heart (v. 5-9)
When sin is hidden in the camp, it produces a distinct and devastating spiritual sickness.
Loss of Courage: The first symptom was that "the hearts of the people melted, and became as water." The holy boldness that brought down the walls of Jericho was gone. Why? Because fellowship with God is the source of all true spiritual courage. When that fellowship is broken by unconfessed sin, our courage drains away, and we are left with nothing but our own human fear.
Confusion in Leadership: Look at Joshua's prayer. It is filled with despair and confusion, bordering on an accusation against God. "Wherefore hast thou at all brought this people over Jordan, to deliver us... to destroy us?" This is what sin does to our prayer life. It clouds our vision. It makes us doubt God's goodness and question His promises. We start asking God, "Why are you letting this happen?" when the real question we should be asking is, "Lord, what is in my heart that is hindering your power?"
