"[Jude] 24-25 The closing doxology repeats and intensifies the note of assurance with which the letter began. The church has good reason to fear (cf. 23); she has no reason to despair. There is One who has the power to bring her safely and triumphantly through all the temptations that beset her into His glorious presence at the Judgement, the Savior God whose eternal glory, majesty, dominion, and authority are all in the service of His mercy, which shall pronounce her blameless on that day. She shall hear Jesus Christ say, "Come unto Me!"
