me it is quite evident that the GT spoken about in Matthew 24, Mark 13 and Luke 21 is a one time, non-repeatable localized event resulting in the destruction of Jerusalem and the temple followed by the dispersion of surviving Jews throughout the nations.
Some scripture is definitely not talking about ancient times but talking about the last days
Mat 24:14 can’t be talking about ancient Jerusalem as the good news had to be preached in the entire inhabited earth before the end would come
