The Scarlet Thread: How Rahab’s Cord Points Straight to the Blood of Jesus

 In the ancient city of Jericho, a single scarlet thread hung from a window on the city wall. That small cord of red became the difference between life and death for an entire family. Today, that same picture still speaks powerfully to every believer. The scarlet thread is one of the most beautiful types of the blood of Jesus Christ found in the Old Testament. It is not just ancient history—it is a living picture of the grace that saves sinners like you and me.

This message is rooted in the infallible King James Bible, Joshua chapter 2, verses 8 through 21. It is directed especially to fundamentalist believers who hold fast to the literal Word of God, but its truth is for every soul who longs to be safe when judgment falls.

The Biblical Account (Joshua 2:8-21, KJV)

“And before they were laid down, she came up unto them upon the roof; And she said unto the men, I know that the LORD hath given you the land, and that your terror is fallen upon us, and that all the inhabitants of the land faint because of you. For we have heard how the LORD dried up the water of the Red sea for you, when ye came out of Egypt; and what ye did unto the two kings of the Amorites, that were on the other side Jordan, Sihon and Og, whom ye utterly destroyed. And as soon as we had heard these things, our hearts did melt, neither did there remain any more courage in any man, because of you: for the LORD your God, he is God in heaven above, and in earth beneath. Now therefore, I pray you, swear unto me by the LORD, since I have shewed you kindness, that ye will also shew kindness unto my father’s house, and give me a true token: And that ye will save alive my father, and my mother, and my brethren, and my sisters, and all that they have, and deliver our lives from death. And the men answered her, Our life for yours, if ye utter not this our business. And it shall be, when the LORD hath given us the land, that we will deal kindly and truly with thee. Then she let them down by a cord through the window: for her house was upon the town wall, and she dwelt upon the wall. And she said unto them, Get you to the mountain, lest the pursuers meet you; and hide yourselves there three days, until the pursuers be returned: and afterward may ye go your way. And the men said unto her, We will be blameless of this thine oath which thou hast made us swear. Behold, when we come into the land, thou shalt bind this line of scarlet thread in the window which thou didst let us down by: and thou shalt bring thy father, and thy mother, and thy brethren, and all thy father’s household, home unto thee. And it shall be, that whosoever shall go out of the doors of thy house into the street, his blood shall be upon his head, and we will be guiltless: and whosoever shall be with thee in the house, his blood shall be on our head, if any hand be upon him. And if thou utter this our business, then we will be quit of thine oath which thou hast made us to swear. And she said, According unto your words, so be it. And she sent them away, and they departed: and she bound the scarlet line in the window.”

Rahab’s Remarkable Faith in a Condemned City

Rahab was a Canaanite harlot living in a city under the sentence of divine judgment. Jericho was wicked; its walls were thick, its people defiant. Yet this woman heard the reports of God’s mighty acts—the drying of the Red Sea, the utter destruction of Sihon and Og—and she believed. She did not merely tremble like the rest of Jericho; she confessed boldly: “the LORD your God, he is God in heaven above, and in earth beneath.” That is saving faith!

The New Testament honors her twice. James 2:25 declares she was “justified by works” when she received the messengers and sent them out another way. Hebrews 11:31 lists her among the heroes of faith: “By faith the harlot Rahab perished not with them that believed not, when she had received the spies with peace.” Even more astonishing, she appears in the genealogy of Jesus Christ Himself (Matthew 1:5). The King of kings has a harlot in His family tree!

The Deep Meaning of the Scarlet Thread

The spies did not give her a rope of any color—they specifically gave her a *scarlet* thread. Blood red. This color is never accidental in Scripture. From the skins of slain animals that covered Adam and Eve’s nakedness, to the blood on the doorposts in Egypt, to the scarlet robe placed on our Saviour’s back, to the crimson stain that washes whiter than snow—the Bible drips with this scarlet thread of atonement.

The instructions were crystal clear: “Bind this line of scarlet thread in the window… and bring thy father, and thy mother, and thy brethren… home unto thee.” The condition was absolute: Stay inside that house marked by the scarlet thread, and you are safe when the judgment falls. Step outside, and “his blood shall be upon his head.” Rahab obeyed immediately—she bound the scarlet line in the window for all to see.

Oh, beloved, can you not see the picture? That scarlet thread is a God-given type of the precious blood of Jesus Christ. Just as the blood of the Passover lamb caused the death angel to pass over Israel, so the scarlet thread caused the judgment sword of Israel to pass over Rahab’s house. Centuries later the Apostle Peter would write, “ye were not redeemed with corruptible things… but with the precious blood of Christ, as of a lamb without blemish and without spot.” The scarlet thread of Jericho points straight to Calvary!

Three Life-Changing Lessons from the Scarlet Thread

1. God’s Grace Reaches the Lowest Sinner

Rahab’s name is forever linked with sin in Scripture, yet God saved her and placed her in the lineage of the Messiah. No sin is too scarlet for the blood of Jesus to wash away. If He can save and use a harlot of Jericho, He can save and use you—no matter how deep your past.

2. True Faith Always Obeys

Rahab believed, but she also bound the thread and gathered her family inside. Faith without works is dead (James 2:17). If you claim to be under the blood but you are still living in the world, still walking in the street of sin, your blood will be upon your own head. The blood only covers those who stay inside the house marked by the scarlet thread.

3. The Scarlet Thread Covers Your Whole Household

Rahab did not say, “Save me and forget the rest.” She brought father, mother, brothers, sisters—everyone who would come. Soul-winner, is your scarlet thread visible to your family? Have you pleaded the blood over your children, your grandchildren, your wayward loved ones? God still honors that kind of faith today.

The Scarlet Thread Today: A Message for Our Generation

We still live in a world under judgment. The walls of this present evil age are cracking. The trumpet of the Lord will soon sound, and judgment will fall. The only question is—are you under the blood? Have you tied the scarlet thread in the window of your life? Have you publicly confessed, “I am trusting only in the blood of Jesus”?

The walls came down on the seventh day when the trumpets sounded. Soon the last trumpet will sound, and this world will fall. The only safe place is inside the house marked by the scarlet thread—the blood of the Lamb.

Will You Tie the Scarlet Thread Today?

If you have never trusted Christ, today is the day. Come to Him. Say with Rahab, “The Lord He is God!” Confess your sin, receive the gospel messengers, and tie the scarlet thread of Christ’s blood over your life by simple faith.

If you are saved but the thread has grown dim, come back today. Rebind it publicly. Gather your family under the blood once more.

And if you are already walking in the power of the blood, go out from this place and tell someone else: “There is a scarlet thread that can save you too!”

The scarlet thread still hangs from the window of heaven. It is the blood of Jesus—nothing more, nothing less, nothing else. Will you come under it today?

In the name of the Father, and of the Son, and of the Holy Ghost, Amen.
