The age ( aeon)in question was the old covenant age that ended in the first century. The great tribulation had to do with the Roman invasion of Jerusalem and the destruction of the temple in that day. Its ancient history.
26 He then would have had to suffer often since the foundation of the world; but now, once at the end of the aeon, He has appeared to put away sin by the sacrifice of Himself. (Heb. 9:26)
However it does not jive with history..nor the present or future... and just because you think this is true does not make it true... and this while tweaking scripture to accomodate your position. Same ol story ...that's been denounced and proven false time and again.
