Kabbalah su Isaia 12:1

93 (53) Said the Soul - Now I am settled, because certainly the way of general rectification comes from the rule of His goodness may he be blessed, but in any event it was His will to act with us only according to our value and not according to His value:

94 (54) Said the Intellect - I will also tell you in regard to this matter an additional detail, and it is - that certainly in every characteristic that He may His name be blessed measures out for us, we can discern two matters, the apparent and the hidden; which means, the apparent is reward and punishment, for whom this characteristic is measured out for according to what it is, the good or the negative; and the hidden is the deep wisdom which is always present in all characteristics, through which to bring all of the creations to the general rectification. For with certainty, this is the character, that there is no action small or large whose essential character of intent is not for the complete rectification, lake the matter that they said (Berachot 60, according to the Ein Yaakov version), "All that is done from the heavens - is good". And these are the words of the prophet (Isaiah 12:1) "...your anger turned back and you consoled me", for the ways of the Holy One blessed is He will be known in the future to the eyes of all Israel how even the rebukes and the tribulations were not other than invitations to goodness, and actual preparation for blessing. For the Holy One blessed is He does not want other than the rectification of his creation, and he does not push away the evildoers with two hands; rather just the opposite, he refines them in the kiln to be rectified, and to emerge cleansed of all slag. And this intent is one for Him may he be blessed in all of his actions that he does with us, to the right or to the left, and we explained above:

206 And it emerges, that when He may He be blessed takes both of these characteristics as one, with concealment of His countenance and illumination of His countenance that we mentioned, the Soul and the Body are born from this, for the matters of the body are less than those of the soul, and there are deficiencies in it which are not in the soul; but there is not negativity within it because of this. Indeed when He may He be blessed wills the innovation of the existence of Negativity, which is the opposite of his actual perfection may He be blessed, as we explained, behold then He concealed His countenance to the greatest extent that one can contemplate, until when He only conceals His countenance and does not illuminate it at all, born from this is the existence of actual deficiencies and creates a destroyer to do damage. And the generality of Negativity emerges, where He may He be blessed removed his right hand backwards from the management of His world, and manages it with sluggishness, by virtue of the darkness of his mystery, and He placed in this nature all of the deficiencies of Goodness, are they not all the characteristics of the court, to bring to justice all that is concealed and the evildoers. And indeed the fury of the Holy One blessed is He is only transient, and its wrath is only to make the snakes and seraphs set aside and invited to purgatory, to strike the evildoer in number according to the measure of his negative behavior:
