(Yechetzqyah/Ezekiel 11:17-20) It makes perfect sense to consider that “perfection” itself would have to be at the very least, an appointed time after Yahshua the Messiah. The book of Hebrews gives us a profound insight when speaking of such things and the prophets of old would have understood such things:
“And all these (prophets of old) have obtained a righteous (“right thinking”) report through faith, have not received the promise (a perfected mind); Yahweh having provided some better thing (the actual revelation of “Yahweh saves”; Yahshua) for us (souls being transformed now), that they (all dead saints), without us, would not be made perfect.” (Hebrews 11:39-40) The earth (mind of man) groans for the perfected ones, that all chosen men (thoughts) past to present would see the perfected ones and be perfected themselves.

Timing is everything:
“For I (Yahweh) will take you (chosen thoughts) from among the heathen (unclean thoughts) and gather you out of all countries (foreign thought centers), and will bring you into your own country (milk = substance in thought, honey sweetness in thoughts). Then I will sprinkle (spread abroad)
the water (spirit) of purification upon you, and you will be clean (mentally washed); from all your filthiness, and from your mighty ones (mental idols), and I will cleanse you. A new heart (mind) I will give (unilaterally) you; and I will take away (out of consciousness) the heart (mind) of stone (rebellion, hardness) out of your flesh (soul life) and give you a heart (mind) of flesh (renewal). I will put My Spirit (the full dose) within you, and cause (total control of thoughts) you to walk in My statutes, and you will keep My judgments (mind verdicts) and do them.” (Yechetzqyah 36:24-
27)

An appointed time of perfection, but for whom? We have one more verse from Yechetzqyah (“may Yahweh strengthen”), but first we go to the prophet (inspired thought) Hosheyah/Hosea (“Yahweh saves”):
“And it will be in that day (the chosen day of full illumination of the mind of Yahweh) says Yahweh; ‘You (chosen souls, chosen thoughts) will call Me Ishi (“My husband”), and will no longer call né Baal: (“Lord”). For I will take away (out of consciousness) the names of Baalim (“Lord”, “God”, “Jesus”) out of her (the perfected congregation) mouth (mind speak), and their names will no longer be called upon! And in that day I will establish (fully institute) My covenant (unilateral mind contract) for them (chosen souls, chosen thoughts) with the animals (untamed thoughts) of the field (thought plain), and with the birds (lofty, unattainable thoughts) of the sky (unknown things), and the creeping (“glide”; crafty, cunning thoughts) things on the ground (the lowest “self”); and I will break the bow (compromise) of the sword (mental piercing), and abolish battle (contention) equipment (“self” reliance) from the earth (mind of man), to make them (chosen souls, chosen thoughts) lie down (rest) safely. I will betroth (mentally wed) you to Me forever; yes, I will betroth you to Me in the righteousness (right thinking), in judgment (just mental activity), in loving kindness, and in mercy (mental compassion); I will betroth you to Me in faithfulness (full faith); and you will know (mental “Oneness”) Yahweh.” (Hosheyah 2:16-20) Yes, it pertains to all souls past present and future but again, timing is everything.
