V.14-15 These two verses should cause us to bow our head in wonder and praise to God. Three men are involved — Enoch, Moses and Jude. Approximately 1,100 years were between the first two, and 1,300 years between the latter two. Not one unsaved person will escape. Nothing was recorded of what Enoch said before Moses wrote the book of Genesis. Secondly, nothing is written in the Old Testament concerning these statements when Jude wrote his Epistle (letter)! So Jude writes that Enoch had prophesied of the judgment of the ungodly when the Lord Jesus comes with ten thousand of His saints! Events around us today, about 2,400 years later, are shaping up quickly so that we are living in the very last days. Always remember that these events will take place 7 years (or close to 7) after we believers are caught up to be with the Lord forever.
V.18 Mockers today? You answer that!
V.20-25 Wonderful contrast for the believer! His responsibility is: building, praying, keeping and looking.
