Matthew chapter 24 mentions the great tribulation it technically doesn't mention Armageddon. DJW:
imho, yes it does! because:
verse 34 describes the generation that will pass away after the end. before that,
verse 21 marks an event of greater destruction than the Deluge (cited again later) , Sodom & Gomorrah, or will ever occur again, so bigger than the post-millenium fire from heaven. therefore, that definition only fits Armageddon. ergo,
"all these things" of verse 34 must include Armageddon, and the generation according to verse 34 survives it, to die later.
Only one group of individuals fit those parameters: the Armageddon survivors that die in the final rebellion, ~ 1040 years from now.
