Note: Don Preston is a full preterist and therefore his teaching cannot receive full or blind acceptance. His many videos on YouTube are worthy of listening and interacting with in a timeline manner.
@2:02: This is my major issue with this portion of Mr Preston's presentation. Even though I agree it is an important theme, I can't accept that it is the theme. And that rejection stems from two things. First, it forces the time text in ways that are unnatural to the prophecies themselves. The second is that it removes the focus from Christ's role as the judge and places the emphatic importance on those vindicated.
But they weren't judged solely for killing the prophets. They had to fill up the measure of the prophet's blood. But Kenneth Gentry demonstrates quiet clearly that the judgment brought upon Israel is one of covenant adultery. The entire book is a seal new covenant because the old bride is being divorced. Both Gentry and Preston are correct. But Gentry's theme is the most important theme in the book of Revelation.
