Take heart, Justinah. Br. Jackson, 2023 AM ~ "Our understanding is clarified according to the proper time and also in a way that will help us not only to endure the great tribulation but also to prosper during that period of time".
Regarding Jerusalem 66-70: The Roman procurator Florus seized 17 talents from the sacred temple treasury. Immediately, the Jews rose up in revolt. Rome reacted swiftly. Within three months there were 30,000 troops appeared on the scene. The Roman soldiers began to undermine the outer wall of the temple. Panic is spreading!
That well describes how suddenly the nations may go after religion. And how religions may respond, by fighting back. How suddenly the GT may start.
Perhaps things will settle down somewhat, after religions have closed down. "On account of the chosen ones, those days will be cut short". This may be compared to when the Roman troops retreated.
However, life never returned to 'normal' in Jerusalem. Within the city rival factions quarreled and fought, much of the food supply was destroyed, and those caught attempting to leave the city were slain as traitors. Josephus relates that in time the famine became so grave that the people were reduced to eating wisps of hay and leather, even their own children.
Those conditions may not be repeated during the GT. Especially if the proclamation of P&S follows the destruction of BtG. The merchants will say "Too bad, too bad, you great city Babylon", but only because of their loss of business.
Br. Jackson said the spiritual food when we need it will not only help us to endure but prosper!
The end came for Jerusalem in 4 months and 25 days, from April 3 - 30, 70C.E. Intense, but remarkably short. No doubt, when Gog attacks us, and those who have joined us, Armageddon will happen promptly.
