But evil isn't necessary for moral freedom for un-created beings? God doesn't need it to be moral?
God is not a being
with qualities like you and I. He
is his qualities, and he
is good. Evil, is simply that which is not in alignment with the good, which is indistinguishable from God. Evil in reality, is the absence of God, and God can never be in absence of himself.
No because God is not a 'being' in the sense that everything else is. Created beings
have qualities, God
is his qualities. He
is what it means to be good.
But if "sin" is the same as "evil" and that is the same as absence of good, then it's nothing you choose. It's just something you lack. Sin is nothing but a hole, not a choice. Or do I understand the whole picture wrong here? (most likely I am, so go ahead and correct me)
Sin is simply any action that is at odds with the moral standards expected by God, in a sense, by sinning you are rejecting God. The more you align yourself with God, the less you will be inclined towards sin, but since on Earth you will never be completely aligned with God you will always have that tendency towards sin. Aligning yourself with God requires a conscious act of will to faith, and to sin requires a conscious act of rejecting God and his moral precepts. You knew something was wrong, but you did it anyway. Sin is not in of itself, a big list of arbitrary "shalt nots".
Sin, grace, moral life, all of it sounds just like mumbo-jumbo words to me. It's so hard to fine-tune the definitions of these words. They are very vague, if you don't mind me saying it.
I've just defined sin.
Grace in essence is the 'friendship' of God. It's your moral standing before God.
A moral life is a life where one strives to live virtuously, and avoid sin. You won't do it perfectly, but it's the unreachable goal to strive for.
The question came back because of your explanation. If God can and wants to, but he doesn't because he can't or doesn't want to, then there's a contradiction. You said earlier "God does not allow evil as a means to bring about the greatest good in of itself ..." Which was confusing. Do you mean that? That free will and moral agency isn't a greater good? Or did you mean something else, and I misunderstood you?
God's designs cannot be frustrated, the presence of evil (or lack of it) is irrelevant as far as God's chances of success are. (Which of course, is certain). Nonetheless evil exists because he has created a world where his creatures are able to choose to commit evil. God knows this and in his foreknowledge has moved to bring about the greatest good despite and even though whatever evil occurs. God has already won, regardless of whatever evil (or lack of evil) may occur. God will use the freedom of beings to his advantage, but his advantage in of itself is not dependant on their choices.
If evil is necessary for us to have free will (that's how I read your explanation above), then heaven either has sin (and free will), or it doesn't have free will (no sin). Is there evil in heaven?
Nothing that is not in full alignment with God can enter Heaven. Begins maintain their freedom and individuality, but their wills are irrevocably aligned with what is good thus making the possibility for sin non-existent among them. Those in Heaven have already made their choice, as those who are in Hell. They have already been tested. Even the Angels were subjected to this choice, and at some point a number (traditionally held to be a third) rejected God and became the demonic.
One reason I started discussion with you was that you seemed to suggest earlier that there wasn't a "greater good".
God is the greatest good, because he is the source of everything that is good. All we are here to do is align ourselves to him and strive for Heaven. But you are in no way obligated to, that's the point of having free will. And you are perfectly free to reject him for you own will. The consequence for this is Hell, but the misery of Hell is simply the consequence of rejecting your own happiness (which is God) not because God is sadistically tormenting you. (Which is a common misunderstanding)
Or... good and evil are two sides of the coin that will never end to exist. It's the two opposing forces that both together must co-exist.
Christians are not dualists. There is no evil in the presence of God, evil is only the absence of him.
