What About Rahab's Lies?

The sermon confronts the moral tension in Joshua 2, where Rahab lies to protect Israelite spies, seemingly violating the Ninth Commandment against false witness, while also upholding the Sixth Commandment to preserve life. Though the narrative presents a complex ethical dilemma, the central message remains clear: Rahab's salvation is grounded not in moral perfection but in faith alone in God's redemptive promise, as affirmed in Hebrews 11, James 2, and Matthew's genealogy. The sermon explores historical Christian attempts to resolve this tension—ranging from claims that no lie occurred, to views of hierarchical moral duties or divine exemption—before advocating that lying to wicked authorities who seek unjust harm is not a violation of truth, since such powers forfeit their right to truth. Ultimately, the sermon redirects focus from ethical debate to the gospel: justification comes not through flawless obedience but through faith in Christ, whose perfect righteousness alone satisfies God's law and saves sinners like Rahab, who were once enemies of God. The call is not to resolve every moral ambiguity, but to trust in Christ as the sole source of salvation, grace, and moral certainty.
