Answer: In Revelation 22:12 (see also verse 20), Jesus declares, "I am coming quickly" to render judgment on mankind.

To God, a thousand years is like an earthly day that has already passed (Psalms 90:4). It is a fleeting moment for God relates to the concept of time in eternal terms. Man could not relate to a day of a thousand years; but he can relate to one of twenty-four hours. As a result, "quickly" used as a promised time interval, must be understood in its simplest earthly definition as occurring in the near future otherwise it is used deceptively. Jesus did not come back "quickly," as promised, to judge mankind. The time has long past that one can claim Jesus will come back "quickly." Thus, what we have in Revelation 22:20 is a false prophecy.
