Genesis 8:22
"As long as the earth endures, seedtime and harvest, cold and heat, summer and winter, day and night will never cease."
No offense, but this hardly seems definitive.
The preterist view has interested me since I left the dispensational camp years ago. Partial preterism make sense to me from a Scriptural standpoint. But, IMO, full Preterism seems Darby-like in its rigid construction. Like Darby, you require everything to conform and throw out hyperbolize those numerous pesky verses.
Actually I see a lot of similarity between Preterists and capital "L" libertarians. They have many good ideas and ask the right questions, but the rigidity of its typical adherents ensures the truths they espouse reach a limited audience.
