Jude 1:15

to execute judgment upon all, and to convict all the ungodly of all their works of ungodliness which they have ungodly wrought, and of all the hard things which ungodly sinners have spoken against him.

This prophecy came quite early in human history; and there is no sacred writer, no apostle, no prophet, and not even the Lord himself, who exercised his ministry, except in the shadow of this promise of a day of judgment when God will settle his accounts with the wicked men who have despised him. The fact of this prophecy colors every page of the Bible; and he is a vain and willful sinner indeed who dares to order his life as if this were not the truth.

Execute judgment ... This phrase occurs "only here and in John 5:27";[44] but significantly, in John it occurs upon the lips of Jesus Christ himself.

Of all the hard things which ungodly sinners have spoken against him ... There is no possibly summary of these that could be given. They are as extensive and voluminous as all the libraries of earth combined. Train loads of books pour out of great publishing houses every month, being directed in a large part, against God, against the Bible, against Christianity, against all truth and righteousness. This characteristic engagement of wicked men in speaking against God manifested itself in a particularly venomous and unreasonable degree during the personal ministry of God in the flesh, Jesus our Lord; and, in this series, we have compiled a list of some 23 vicious lies and slanders that were launched against Christ by evil men.
