Liar, Liar

John 8:42-47

“When [the devil] lies, he speaks his native language, for he is a liar and the father of lies.”

— John 8:44

A lie led to the beginning of human sin. Back in the Garden of Eden, Adam and Eve accepted Satan’s lie: “You will not certainly die. . . . You will be like God, knowing good and evil” (Genesis 3:4-5).

Ever since then, the voice of the liar, the father of lies, has carried on. Satan apparently can’t speak the truth; lying is his native language. Today Satan keeps telling us versions of the same lies he spoke in Eden: “God doesn’t really want the best for you.” “You will never have any fun if you follow the moral standard set by God.” “You really won’t suffer any consequences for doing that.”

What lies is Satan telling you lately? “It really doesn’t matter if you watch some porn.” “Paying all your taxes would be crazy, given the way the government spends money.” “You deserve a new car, a new sex partner, a higher salary.”

Pay attention to what you are thinking. Listening to the father of lies can be the first step into sinfulness.

These lies include conspiracy theories that flood social media. Satan is in charge of those too. He is quite capable of using politicians and media personalities to promote his lies. The fact that others may agree with Satan is no excuse.

Our thought world is a war zone. Listen to the one who has already won the war. Reject the one who can never be trusted.

Father, we are surrounded by lies. We hear them at every turn. Help us to recognize and reject them. May we reject the father of lies too. In Jesus’ name, Amen.
