3. (a) Why is fornication such a serious wrong? (b) What is the aim of Satan the Devil?

³ What Julie had been fooled or tricked into doing was a serious violation of God’s law. For that reason the Bible urges: “Flee from fornication.” And it states plainly: “No fornicator . . . has any inheritance in the kingdom of the Christ and of God.” (1 Corinthians 6:18; Ephesians 5:5) So while Satan the Devil may not be concerned whether you win or lose a ball game or you make a wise purchase or not, he is definitely trying to mislead you into breaking God’s law. “Your adversary, the Devil, walks about like a roaring lion, seeking to devour someone,” the Bible warns. (1 Peter 5:8) Indeed, he is using all his shrewd thinking, including posing as an angel of light, to get us away from serving Jehovah God! Is that not a sobering thought?​—2 Corinthians 11:14.

5. (a) What should we never be lulled into thinking? (b) What was the apostle Paul’s concern, and why was it appropriate?

⁵ Never be lulled into thinking that Satan’s methods could not work on you, that he could never get you to break God’s laws. Remember the divine warning that “Satan himself keeps transforming himself into an angel of light.” (2 Corinthians 11:14) The apostle Paul was rightly concerned that the Master of Deception might be successful in his approaches to Paul’s less experienced fellow Christians. Paul wrote: “I am afraid that somehow, as the serpent seduced Eve by its cunning, your minds might be corrupted away from the sincerity and the chastity that are due the Christ.”​—2 Corinthians 11:3.
