Outline: The Scarlet Cord in the Window
Theme: There is a sign upon this house
Base Text: Joshua 2:18-21
"...you shall tie this scarlet cord in the window through which you let us down."
---
Introduction
Many windows in Jericho. Only one scarlet cord. Likely the very rope Rahab used to lower the spies (v. 15) — an ordinary object made into a sign.
---
1. The Sign Was Given, Not Chosen
Support: Joshua 2:18 — the instruction comes from the spies, not from Rahab
She asked for a sign of protection (v. 12); she did not get to decide what it would be.
To develop: God establishes the terms of salvation — we don't negotiate them.
2. The Sign Had to Be Visible
Support:"in the window" — visible from outside, in a city that was shut tight (Joshua 6:1)
Hanging that cord was a public declaration that she had changed sides.
To develop: hidden faith versus confessed faith.
3. The Sign Defined a Boundary
Support: Joshua 2:19 — inside the house, protected; outside the door, not so
To develop: the connection to "Save your household."
4. The Sign Required Staying Power
Support: Joshua 2:21 — "she tied the scarlet cord in the window" — immediately, and it stayed there until the city fell
It wasn't hung out only when the army appeared on the horizon.
To develop: obedience that doesn't wait for the emergency.

A Note on Typology (important)
The text of Joshua does not state that the scarlet cord represents the blood of Christ. Preach it as an echo, not as an explicit claim of the text:
Echo of the Passover: a red mark on the entrance of a house, and the destruction that passes by (Exodus 12:13). The pattern is the same.
Ancient church reading: Clement of Rome, writing at the end of the first century, already saw here a figure of redemption.
A linguistic detail: the Hebrew word for "cord" (tiqvah) shares its root with the word commonly translated as hope — a hope hung in the window.
The power lies in the resonance. Don't force the text to say what it doesn't say — the theological point stands on its own without it.
---
Practical Application
Identify the sign God has established — not the one you invented for yourself.
Ask whether your faith is visible or kept out of sight.
Consider who is inside your house.
Hang the cord today, not when the siege is already closing in.

Conclusion and Appeal
Jericho had walls, and they fell. One house with a scarlet thread was left standing.
Appeal: The question isn't whether you are strong — it's whether there is a sign upon your house.
