What does Jude 1:15 mean?
This continues a quote, begun in the prior verse, most likely adapted from the non-inspired Book of Enoch. Jude has spent a great deal of effort explaining how dangerous false teachers really are. A particularly important moment came in verse 12, where he referred to them as "hidden reefs." This emphasizes how their sins and errors can be subtle, even invisible, until they suddenly cause a catastrophe in someone else's spiritual life. Because these men have rejected the truth in favor of their own preferences, Jude makes it clear that they're destined for eternal punishment (Jude 1:13).Here, again, Jude reminds his readers of the fate of false teachers and all who reject or distort the truth. When the Lord returns to Earth with thousands of His angels and raptured believers, He will judge them and convict the ungodly of their foul deeds and ruthless insults they have hurled against Him (Matthew 24:30; 2 Thessalonians 1:9–10). The apostates will be judged by Jesus, the one of whom they had spoken abusively (Jude 1:4, 1:8).
