Because the teachers of false doctrine do wicked things, God will condemn them to hell. They are dangerous, useless, spiritually dead, restless, shameless, and unreliable.

Jude 11-13

11 God will do terrible things to those who teach false doctrine! They conduct their lives wickedly like Cain, who murdered his brother because he was ◄jealous/angry because God accepted his brother’s sacrifice and did not accept his►. These false teachers ◄devote themselves to [MET] doing wrong things like Balaam, who tried to induce God’s people to sin in order to get the money that was offered to him. They will perish like Korah, who rebelled against the authority that God gave to Moses. 12 Those teachers of false doctrine are as dangerous to you as [MET] ◄hidden rocks on a reef/rocks underneath the surface of the ocean► are to a boat. When you gather together to eat the meals that help you believers to love each other more and have a closer relationship with each other, they join you and carouse shamelessly, caring only for themselves and not for others. Because they do not do anything to help others [MET], they are as useless as clouds that are blown along by the wind {that the wind blows along} but that do not produce/give any rain. They are as disappointing as [MET] trees that do not produce fruit in the autumn as we expect them to. They are not only spiritually [MET] dead themselves, but they are not able to cause others to be alive spiritually, just like [MET] trees that have been {that someone has} uprooted and as a result are unable to produce any fruit. 13 They are restless [MET], like the pounding waves of the ocean. Just like waves produce foul-smelling foam on the shore, those teachers of false doctrine do shameful [MTY] deeds. We cannot depend/rely on them to show us how to conduct our lives [MET], just like we cannot depend/rely on ◄meteors/falling stars► to show us the way when we travel. God has reserved intense darkness for them forever in hell.
