"It was also about these that Enoch, the seventh from Adam, prophesied, saying, Behold, the Lord comes with ten thousands of his holy ones, to execute judgment on all" - Enoch essentially prophesied the flood!

"and to convict all the ungodly of all their deeds of ungodliness" - bad people do bad things...

"that they have committed in such an ungodly way," - ...in bad ways. Sin is so thoroughly a part of the apostate's life that it laces everything they are and everything they do...

"and of all the harsh things that ungodly sinners have spoken against him." - ...and everything they say. They speak against the God they claim to worship.

Jude 1:14-15
