What does the scarlet cord represent in the Bible?

The scarlet cord in Joshua 2 symbolizes the blood of Christ and His sacrificial redemption for sinners. Just as Rahab hung the cord to signify her faith and secure her family's salvation, believers today recognize this symbol as a profound picture of Christ's atoning work. Rahab, despite her background, becomes an instrument through which God demonstrates His grace, illustrating that salvation is not bound by human merit but grounded in Christ's sacrifice. This picture showcases the glory of God in saving chosen sinners through the blood of the covenant.
