Oddly enough, most "fundamentalist preachers" don't teach this, either.
Nevertheless, a good foundational piece.
Most of the Book of Revelation is Prophecy future.
Daniel, Isaiah, Ezekiel and many of the other prophets
as well as the New Testament clearly define prophecy
that pertains to the end times, or the Day of the Lord, or in the last days, etc.
This egghead seems to be trying to create a problem where there isn't one.
