the darkness is freedom, it was made by God denying himself out of love. but the darkness, in being denied, has lost it's enlightenment. and so out of darkness may come anything since it is irrational. from it comes good and evil, though it would not be so if it was divine. but the darkness is not evil of itself, it is because of love and desire inside of God. darkness is a means of God revealing himself within himself, he finds his other and his other finds him and they together make the kingdom of heaven.
spiritual iniquity is anything less than God. you can not have self-love unless you count God as yourself as well, otherwise it is satanic, blind, evil that rejects God. you can not truly reject yourself if you accept God, because you reject yourself that you may be with God, thus all you rejected was anything that rejected God. because God loved us so much that he denied himself, because he had to give us freedom. but he wants a loving reflection as well. he wants our love. he deserves our love. we want his love. we deserve his love.
evil is the manifestation that says "this is what i am without you God". if it was okay and good then God would let it be forever, but it is not so, because in eternity there are three revelations and from before eternity God saw it was not good that man be alone nor did God want to be alone, because God loves man so much that he became man and he wants us to become his son in freedom, not by just necessity and lack of freedom, because if an accidental good was good enough then it would have remained forever but since God has other plans, namely, that love and freedom can not be separated, for it is unworthy of God. but God deserves to be loved freely because he freely loves.
but the sacrifice was his emptying out of himself that we become revealed within him, since we have always been super-united to God. it is strange to speak about God since his processes are not logical, as they are just what he does and is. it is reality. it is not a secondary image, though it comes out that way.
it is absurd to believe that a kingdom of evil would be forever, because it never was as God and his other would make sure of that, even if it would be allowed for the sake of freedom for a season. only the kingdom of heaven is eternal. but we have to each pick up our cross, be free and find God and be with him. because evil will be until it goes away. but there is no doubt, it was destroyed, it is contained within systems of creation, since that is as powerful as it could ever be, for God is not created, he is the creator. but evil is the degradation of the good creation, and thus it can only 'exist' if it has some goodness to parasite and distort. but goodness would never ruin itself if it was fully aware and with God.
