Excellent point.
EVERYTHING rests on a date for Revelation of about 70 AD.
All of prophetic literature and especially that regarding the return of Christ is dependent on this dating. The reverberations of this teaching touch on other doctrine as well.
Is it any wonder that they also must discount the sacrifices of the Ezekiel Temple? And their argument is that those cannot be symbolic.
What does that do to the Book of Hebrews that clearly states that ALL OF THE OLD TESTAMENT SACRIFICES were symbolic....looking forward to the sacrifice of Christ?
Are we now to believe that the blood of bulls and goats COULD take away sin?
If you read the OT literally and ignore the NT, they they could. Oops. I just applied dispensational hermeneutics.
