The "hour" of "trial" or "temptation" I might see as a collective dividing process, exactly similar to the same account found in Matt. 25 and in other places throughout the scriptures, which has been promised upon the "whole" earth.
It stems from the Promise of Jesus, here:
Luke 12:
51 Suppose ye that
I am come to give peace on earth? I tell you, Nay; but rather
division:
52 For from henceforth there shall be five in one house divided, three against two, and two against three.
53 The father shall be divided against the son, and the son against the father; the mother against the daughter, and the daughter against the mother; the mother in law against her daughter in law, and the daughter in law against her mother in law.
54 And he said also to the people, When ye see a cloud rise out of the west, straightway ye say, There cometh a shower; and so it is.
55 And when ye see the south wind blow, ye say, There will be heat; and it cometh to pass.
56
Ye hypocrites, ye can discern the face of the sky and of the earth; but
how is it that ye do not discern this time?
57
Yea, and why even of yourselves judge ye not what is right?
It is a personal matter of "engagement." That's also why the notions of a collective "unified" resistance of the flesh, which the Spirit is and remains "actively" against (Gal. 5:17) won't happen. Like all the unbelievers gathered under some flesh anti-Christ. It's just not going to happen. What will happen is every man will be against another, even his brother:
Jeremiah 25:31
A noise shall come even to the ends of the earth; for
the Lord hath a controversy with the nations,
he will plead with all flesh;
he will give them that are wicked to the sword, saith the Lord.
Ezekiel 38:21
And
I will call for a sword against him throughout all my mountains, saith the Lord God:
every man's sword shall be against his brother.
God has promised to keep enemies divided. We see this active promise everywhere on the earth, really, since the start of this current wicked age (since Adam.) The end time will culminate this matter.
Believers in Rev. 3 have already been "pre-divided." That is why they will not suffer this particular form of division. The source of this pre-division is found here:
Luke 14:26
If any man come to me,
and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and
his own life also, he cannot be my disciple.
Believers who have already gone through this will understand, and will not be "as" confused when that time comes. They'll understand that they are standing, in their own flesh, in the battle ground. And they'll see how God "actively" deals with our adversaries in the here and now.
It happens, daily, after the Ways that God has already set and shown in His Words. I might term it "the collective insanity" of the flesh, exhibited daily, promised to increase to the end.
