Because those teachers of false doctrine will entice people to behave wickedly, God has reserved darkest hell for them.

2 Peter 2:17-22

17 These teachers who each false things mislead/deceive people by promising what they cannot do, as [MET] dried-up springs mislead/deceive people by causing them to expect to get water from them. They mislead/deceive people [MET] just like clouds that are blown along by strong winds mislead/deceive people by causing them to expect rain, but no rain falls. Therefore, God has reserved the darkness of hell for those teachers of false doctrines. 18 By boasting proudly as they make speeches that are worthless, they entice people who have recently become believers and have stopped doing the things that wicked people do. Urged on by their self-directed nature, they entice them into sin by encouraging them to do evil things. 19 The false teachers tell people that they are free to do whatever they want to do, even though they themselves are like slaves [MET] because their own self-directed nature forces them to do sinful things. Think about these well-known words: “Whenever a person is controlled by something {something controls a person}, it is as though that person has become a slave of what controls him.” 20 Those who teach false truths learned about our Lord and Savior Jesus Christ. As a result, they stopped doing those things that ◄defile people/cause people to become impure► spiritually. Since they have begun to do those evil things again, with the result that they are unable to stop doing them, they are in a worse condition than they were in before they knew Jesus Christ. 21 Because God will severely punish them, it would have been better for them if they had never known what it means to live in a righteous way. It is too bad that although they knew how to live in a righteous way, they stopped doing the things that God commanded people to do, the things that were taught to them ◄by us apostles/by Christ► {that ◄we apostles/Christ► taught to them}. 22 The way they are behaving again is just like ◄the proverbs/what people often say►: They are like dogs that return to eat their vomit, and they are like pigs that have been washed and then roll again in the mud.
