We may have equal fruit of converts with Noah!

Observing Pr 2:
[6] For the LORD giveth wisdom: out of his mouth cometh knowledge and understanding.

...we see that one good and perfect gift (Jas 1:13) that God gives us is "understanding." I infer that he doesn't use the square distribution system to "not respect persons," (Ro 2:11,) by the verses in 2 Cor 3:
[13] And not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished:
[14] But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.
[15] But even unto this day, when Moses is read, the vail is upon their heart.
[16] Nevertheless when it shall turn to the Lord, the vail shall be taken away.

The square distribution would give all men equal understanding. I suppose the "vail" is accorded notice in our current language (Ps 19:3,) in the phrase, "pull the wool over his eyes." It is interesting that in the current day, the textile obscuring the vision of the intellect is "wool," a product inextricably linked to the common Israelite herder illustration, Sheep. It is as if to say, "Christians themselves are the reason worldly people cannot understand!" (1 Cor 2:14.)

A physical manifestation of the New Covenant being ratified may have been Mt 27:
[50] Jesus, when he had cried again with a loud voice, yielded up the ghost.
[51] And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent;

I don't know why the New Testament Authorized Version accords itself two spellings, but it is intriguing. Perhaps it is to avoid the literalistic requiring just such a literal rendering exhaustively.
It also quietly accommodates a speedy consummation theory of Eph 5:
[32] This is a great mystery: but I speak concerning Christ and the church.

...he died and the veil was torn immediately.

Other than that, God's fulfillment of Lk 18:
[7] And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?
[8] I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth?

... would be on a timetable of a thousand years 2 Pet 3:8. It is because of just such considerations that the latter half of verse 18 remains an open question. A “Rapture” can't happen on an earth where there is no Faith. 2 Thess 4:16 was optional, conditional on contingencies we can anticipate but not prove.

Another commentary on the Lord's timetable is in Ro 9:
[27] Esaias also crieth concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved:
[28] For he will finish the work, and cut it short in righteousness: because a short work will the Lord make upon the earth.

This follows a Hosea quote, and is non-specific about how the haste in question is to be accomplished. One theory on how, is that it will be similar to the US Desert Storm (in 100 hrs,) after Desert Shield prep work for 6 months.

When Christ comes again, (Ro 14:
[11] For it is written, As I live, saith the Lord, every knee shall bow to me, and every tongue shall confess to God.)

...the phrase "shock and awe," will take new meaning one last time.
