²⁷ For the Son of Man is going to come with his angels in the glory of his Father, and then he will repay each person according to what he has done. ²⁸ Truly, I say to you, there are some standing here who will not taste death until they see the Son of Man coming in his kingdom.  -  Matthew 16:27-28

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.

@1:34: Mr Preston is absolutely correct that these verses cannot be displaced from each other. I'm not convinced by Isaiah. I'm convinced because there is no exegetical reason to delineate the two. Isaiah certainly works to confirm the application of the preterist opinion however.

@4:20: I completely agree with the fact that the two verses are tied together.  I'll agree with Mr Preston's suggestion that this happened at the fall of Jerusalem as well. Part of my reason for this is that I feel it helps explain the entirety of Matthew 25 and its unique judgment. 

I need to give a little insight on that previous statement. To some it may cause concern that I view Matthew 25 as already accomplished in the destruction of Jerusalem. The reason for that concern is because the phrase "weeping and gnashing of teeth" (Matt 25:30) and "eternal punishment" (Matt 25:46) have been read to mean the final judgment.

In brevity, the parable of the virgins ends with language from the previous chapter (Matt 24:36, 44, 50; 25:13) and Christ reveals Himself in glory with His angles (Matt 25:31) in Matt 16 type language. 

I say all that to explain my preteristic opinion of Matthew 25 while reiterating that I don't deny a future judgment of the dead (as per John in his gospel, epistles and apocalypse). In the future I will provide more insight to my opinion of gospel texts that have led me to this view.
