What the Bible Says About Lying

The Bible treats lying as a serious sin because it strikes at the very character of God, who is truth and cannot lie. The ninth commandment forbids it directly: "You shall not bear false witness against your neighbor" (Exodus 20:16). Leviticus 19:11 broadens the principle beyond the courtroom to all of life: "You shall not lie to one another." Truthfulness is woven into the fabric of God's covenant community, because deceit destroys the trust on which all relationships and justice depend. When we lie, we mar the image of the God of truth that we are called to reflect. The book of Proverbs returns repeatedly to this theme. "A lying tongue" is named among the things the Lord hates in Proverbs 6:17, listed alongside pride, violence, and discord as detestable to Him. Proverbs 12:22 states it pointedly: "Lying lips are an abomination to the LORD, but those who act faithfully are his delight." And Proverbs 19:9 warns that "a false witness will not go unpunished, and he who breathes out lies will perish." These sobering words reveal that deception is never harmless; it carries real consequences and provokes God's displeasure. For the believer, truth-telling is part of the new life in Christ. Paul commands in Colossians 3:9, "Do not lie to one another, seeing that you have put off the old self with its practices." Honesty flows from a transformed heart that no longer needs the cover of deceit. Revelation 21:8 issues the most solemn warning of all, placing "all liars" among those whose portion is judgment apart from repentance, while truth marks the citizens of God's eternal city. Yet the gospel offers full pardon: the God who hates lying lips delights to forgive the repentant and to fill them with His Spirit of truth, reshaping them into people who speak honestly, keep their word, and reflect His own faithful character.
