Keep On Resisting
Jude next gave advice on resisting bad influences. (Verses 17-25) There would be ridiculers in “the last time,” and true Christians must endure them and their taunting words today. To resist such bad influences, we should build ourselves up on our “most holy faith,” pray with holy spirit, and keep in God’s love, while waiting for Jesus’ mercy to be expressed.
Apparently in the role of false teachers, the ungodly men caused some to have doubts. (Compare 2 Peter 2:1-3.) And what did doubters need? Why, spiritual help to be snatched out of the “fire,” everlasting destruction! (Matthew 18:8, 9) But the godly need not fear that destiny, for Jehovah will protect them from “stumbling” into sin and the destruction awaiting apostates.

Antidotes for Sin and Apostasy
Is there a restraining brake against practicing sin? John’s answer is: “He that does not love has not come to know God, BECAUSE GOD IS LOVE.” Thus, with striking simplicity, John drives home his point. Love is the key. And God’s love expressed through his Son is the antidote for sin’s effects. “By this the love of God was made manifest in our case, because God sent forth his only-begotten Son into the world that we might gain life through him.” How should this knowledge affect us? John answers: “Beloved ones, if this is how God loved us, then we are ourselves under obligation to love one another.”—1 John 4:8-11.
If we truly love God and neighbor, then we will resist the inroads of sin and apostasy. Love does not willfully go against God’s laws and principles. Nevertheless, John warns: “There is a sin that does incur death.” Unrepentant apostates would certainly be in the category of those who merit destruction.—1 John 5:16, 17; Matthew 12:31; Luke 12:10; Hebrews 6:4-6; 10:23-27.

15 Since those false teachers did not maintain a steady course in righteousness, they were like “wandering stars.” (Authorized Version) Of course, navigation by the stars would be impossible if these unpredictably wandered about. Accordingly, like stars having no “set course,” those apostates could not be depended upon for sound spiritual guidance. For those false lights God “reserved” nothing but the “blackness of darkness” eternally, and this signified their everlasting destruction. For many reasons, indeed, faithful Christian witnesses of Jehovah completely reject false teachers and their doctrines.
*** w84 7/1 p. 13 “The Battle Is Not Yours, but God’s” ***
That last article, "The Battle Is Not Yours..." in effect encourages what you suggested. But it doesn't do so in a direct sentence. It gives the example of Jehoshaphat and compares his adversaries to apostates. His solution was prayer and his prayer was answered in the form of destruction.
Of course, nothing in the Bible account actually compares their foes to apostates on that occasion, but such trifles have never troubled the Watchtower boys.
The article w82 9/1 "Look! Jehovah Came With His Holy Myriads" lays out beautifully why I left that apostate organization. I "completely reject false teachers and their doctrines."
