Kabbalah su Isaia 25:1

83 And know as well, that certainly now as well, even though He has hidden His goodness and withheld the rule of His perfection from the creations, even so it is certain that He sustains them, for from where else would their being and existence and maintenance come if not from His sustenance. If so certainly He is the sustainer, but this sustenance of His that he provides now - in comparison to that which would be appropriate for him to provide if He were sustaining according to the rule of his perfection he wished to provide sustenance - is not other than a shadow for man, or like a small mark that remains from writing on paper after the letters have been removed from it. And we would call the general type of this sustenance - darkness and not light, with regard to the complete sustenance which could come if through the rule of His perfection he were to provide sustenance. Indeed with regard to ours this is all of our lives, for with this sustenance we live and exist, and not without it. And we find, when we mention the type of this sustenance which is innovated in the hiding of the countenance of His goodness may He be blessed, we call them with one generalization - like the shadow of the heavenly power alone, not more; and when we dissect it to its details - we find within it all the rules and laws which we discern in the heavenly behavior, for all of them together are a very small thing relative to the heavenly power if He were to act in his completeness, as I mentioned:

84 And indeed when the ultimate purpose is only revelation of the Singularity, and not its concealment, and like we explained before, that this concealment is only intermediate in order to come to this end of revelation; therefore, even though the concealment of His countenance is to innovate with it this manner of behavior of good and negative, He returns nevertheless and oversees with the characteristic of goodness and according to the law of his rulership, to complete bringing about all of this behavior in the general rectification. And this is a simple matter, since ou have already heard how He set a time limit to the this darkness of the good and negative all the time of the six thousand years; and He already decreed from the beginning the end which is the purpose of all of this, and His Singularity will remain revealed, and the goodness of the world will be established forever and ever. If so, every day that passes, we find the world coming closer to its perfection; and not only this, rather that the Holy One blessed is He brings about overturning through the depths of his wisdom, and continuously revolves transformations, to bring the world towards this perfection. And this is what the text said (Tehilim 40:6), "Many things have you done HaShem my Lord, your miracles and thoughts are towards us..."; and similarly said the prophet (Isaiah 25:1) "...Counsel from the past is faith for the faithful"; and similarly it is said (Samuel II 14:14) "...and he plans so that the exiled will not remain exiled". For certainly the Holy One blessed is He does not want to hold to the way of Good and negative for such a long time, and afterward to abandon it and to grasp the way of rulership and Singularity in one moment, like a person who regrets and is consoled; rather from the depths of His wisdom may He be blessed he revolves the events from the depths of his wisdom such that, from within the Good and negative itself in the end we reach this point, that all will be completed, and He may His name be blessed will reveal His Singularity. And more will be explained from this later with the help of heaven:
