Question: "What does the Bible say about lying? Is lying a sin?"
Answer: The Bible is clear that lying is a sin and is displeasing to God. The first sin in this world involved a lie told to Eve. The Ten Commandments given to Moses includes “You shall not bear false witness against your neighbor” (Exodus 20:16).
In the early church, Ananias and Sapphira lied regarding a donation in order to make themselves look more generous than they really were. Peter’s rebuke is stern: “Ananias, why has Satan filled your heart to lie to the Holy Spirit?” God’s judgment was sterner: the couple died as a result of their sin of lying.
Colossians 3:9 says, “Do not lie to each other, since you have taken off your old self with its practices.” Lying is listed in 1 Timothy 1:9-11 as something practiced by the lawless. Furthermore, liars will be among those judged in the end (Revelation 21:8). In contrast, God never lies (Titus 1:2). He is the source of truth. “It is impossible for God to lie” (Hebrews 6:18).
Jesus called Himself the way, the truth, and the life (John 14:6), and He expects those who follow Him to be people of truth. The truth is to be expressed in love (Ephesians 4:15), offering hope to those seeking redemption from the lies of the world.
