Is deception always wrong?

Exodus 20:16You must not testify falsely against your neighbor.

Leviticus 19:11Do not steal. Do not deceive or cheat one another.

Proverbs 24:28Don’t testify against your neighbors without cause; don’t lie about them.

Colossians 3:9Don’t lie to each other, for you have stripped off your old sinful nature and all its wicked deeds.

One of God’s Ten Commandments calls us to tell the truth. It is simply wrong to deceive others to gain a personal advantage.

1 Peter 2:22He never sinned, nor ever deceived anyone.

Jesus never lied or deceived anyone, and he is our model for right and wrong.

Joshua 2:4-6Rahab had hidden the two men, but she replied, “Yes, the men were here earlier, but I didn’t know where they were from. They left the town at dusk, as the gates were about to close. I don’t know where they went. If you hurry, you can probably catch up with them.” (Actually, she had taken them up to the roof and hidden them. . . .)

Hebrews 11:31It was by faith that Rahab the prostitute was not destroyed with the people in her city who refused to obey God. For she had given a friendly welcome to the spies.

There are times in Scripture when a person lies to protect another from harm, as Rahab did for Israel’s spies. Some scholars believe that people who ask questions with the sole purpose of harming others forfeit their right to be told the truth, especially during a time of war. During war, you cannot aid the enemy just because someone asks you to. Since the only goal of the king’s soldiers was to capture and eventually kill the Israelite spies, they gave up their right to be told the truth about the spies’ location. You don’t oppose deception by betraying innocent people.

Another viewpoint, however, is that God never needs, wants, or asks us to sin in order for him to accomplish his will. Rahab obviously had to think quickly, and lying was the only thing that came to mind. While Scripture does not explicitly condemn Rahab for her lie, it does make it clear that lying is wrong (Exodus 20:16; Leviticus 19:11; Proverbs 6:16–17; 12:22; 24:28). But God was merciful and continued with his plan despite Rahab’s lie. While Rahab’s act may have been wrong, depending on your viewpoint, her motives were good (to save God’s people). Perhaps that is why God was merciful. The Bible commends her faith (Hebrews 11:31) but not her lie.

Revelation 21:8But cowards, unbelievers, the corrupt, . . . and all liars—their fate is in the fiery lake of burning sulfur.

Revelation 21:27Nothing evil will be allowed to enter, nor anyone who practices shameful idolatry and dishonesty—but only those whose names are written in the Lamb’s Book of Life.

The Bible makes it clear that deception is a sin.
