Jesus did come to "seal up prophecy".
"Seventy weeks are determined For your people and for your holy city, To finish the transgression, To make an end of sins, To make reconciliation for iniquity, To bring in everlasting righteousness, To seal up vision and prophecy, And to anoint the Most Holy." (Dan. 9:24)
The final week of Daniel 9 was the time of Christ's coming to redeem His people and establish His church of both Jews and gentiles, the true sons of Abraham.
Only the gap theorists can argue for "vision and prophecy" after the 1st century.
Well TC, it appears that you have a GAP as well. After the 69th Week the Messiah was to be cut off. That was the crucifixion. That left one week (7 years) for the fulfillment of all prophecy. That would mean that everything in the book of Revelation and the Book of Daniel would have to have been completed by AD 40.
Yet you claim that the 70th week was not fulfilled until 70 AD. So, you've got a Gap! So no matter whether you are a hyper-preterist or a hyper-dispensationalist, you've got to account for the suspension of the prophecy between the 69th and 70th week.
