Yes, God did preordain evil for good.
HE ordained evil be USED for good among sinners.
HE did NOT create evil so good could be enhanced:
Predestination to Damnation before Creation Serves HIS Purpose?
Others have suggested that GOD
"before life" loved only some because this is more beneficial for HIS purposes than if HE before life loved everyone. This
'before life' love is expressed in HIS loving election of some to salvation and HIS not loving others as expressed in their being passed over for election to salvation before the foundation of the world, ie, earthly life.
The explanation goes something like this:
The loved ones' eternal joy is directly proportional to their knowledge, appreciation, of GOD and the wonderfulness of their salvation. Therefore an increase of good comes forth from the eternal damnation of some persons because by their damnation, that is, the outcome of Adam's decision to sin, and HIS "before life" decision not to love these persons, two types of eternal blessings supposedly occur for the rest.
First, a fuller appreciation of several of God's attributes is made possible, which opportunity wouldn't be possible if all lived forever, that is, if HE "before life" loved them all. These attributes are usually said to be HIS justness (retribution, wrath) holiness and omnipotence.
Secondly, the truth regarding the non-elect's end apart from Christ's salvation is made fully known, which full knowledge makes possible the fuller appreciation of HIS salvation, for this salvation (hence, HIS mercy too) would not be so fully appreciated without the graphic depiction of both states of after earthly life.
Others even go so far as to say that their damnation is absolutely necessary in order that the purpose of GOD be able to be fulfilled by HIS elect, and they offer this explanation:
In order to live in eternity with GOD, we must live fully in the truth, which necessity necessitates having a perfect appreciation of GOD's attributes and HIS salvation, and that this perfect appreciation by HIS elect creatures is made possible first, only through witnessing HIS triumph over and judgement upon HIS enemies, and second, only when HIS perfection and our life in Christ are contrasted with the complete imperfections of the damned and the end we would have had, had HE not saved us.
Now, these are very hard positions to hold, for they fail on many accounts.
First, they both fail to answer or give a reasonable basis for why HE chose the particular ones HE did and why HE did not choose the rest. In other words, they both deny the faithful, just and unselfish character of GOD's love, in that they limit it without just cause and look on it as somewhat capricious.
Secondly, they both necessitate the unproven presupposition that it is impossible for GOD to perfect HIS creatures HIMSELF, that HE needs the presence of evil in order to bring HIS creation to its highest potential of understanding and appreciation.
In other words we must accept, for example, that in GOD’S world one has to first be sick in order to be healthy, or sinful in order to be faultless [and the more sinful (or sick) the better].
Third, they both fail to satisfactorily answer the question of how the damnation of millions makes us more appreciative / perfect than the damnation of but one, since it is the moral depravity of those in hell that is supposed to make for the increased appreciation, perfection and not the quantity of persons therein.
Fourthly, they both put a very small value on the worth of the individual creature in the eyes of GOD, contrary to Christ's words about the value of each person in GOD's sight.
Well, since a reasonable answer has not been put forward for GOD's foreknowledge / forelove before the foundation of the world not including everyone, we are left with but two conclusions:
We must either look for the answer elsewhere, in some area we have not looked before, or we must put the basis of HIS foreknowledge down to unreasonable chance.
This would mean that there is no reason for HIS particular "before life" love. [Aside: as I understand it, this is Calvin's position, his failure to understand this doctrine correctly.] GOD's election / foreknowing is thus based on eenie, meenie, minie, mo, but how can you put your faith in a GOD like that? How much better to admit that we should start looking in some area we have not looked yet, and since we cannot find any of those, why not finally admit that we need a revelation from GOD to give us an infinitely loving answer to this problem?
Now, according to others, the "before life" love (foreknowledge) of GOD, that is, HIS pre-life approval of some and rejection of the rest, is based on the prior uncoerced choice of the creature (in Sheol, before physical creation) and on HIS infinite love, which means that HE will never stop loving anyone who can possibly ever come to glorify HIM.
