evil and Gods will

abstract (summary): "evil is the absence of God, so he has the ability to cause it by leaving someplace"

This will be a high-tension controversial theory and I'd like to resolve into something more certain if possible. If bible verses and other thoughts come into your head as you read, I would love to hear them.

Evil is not directly opposed to God, as if we could pick up evil and throw it at him. When God comes in contact with evil, there is no battle (naturally). Evil is only the absence of God, like dark is the absence of light. So when God moves into a dark corner...he lights it up - no questions asked, no battle.

So now regarding the presence of evil and God's absolute soverign will. Everything that happens is part of God's plan, right? But what about evil? Does he make us do evil sometimes?
James 1:13-14 "When tempted, no one should say, 'God is tempting me.' For God cannot be tempted by evil, nor does he tempt anyone; 14 but each one is temted when, by his own evil desire, he is dragged away and enticed."
Exodus 10:20 "But the LORD hardened Pharaoh's heart, and he would not let the Israelites go."
Hm. I don't have an acceptable solution to this yet.

Here's one 'solution' which is not really satisfactory. Could God create evil by simply leaving someplace? For instance, could he retract his gracious hand of sanity from Pharaoh's heart, causing him to have a hard heart? This unfortunately makes God very closely connected with evil. Any thoughts on this subject would be appreciated!

More texts: Romans 9 in general.
Romans 1:24,26 "Therefore [because people had rejected God] he gave them over in the sinful desires of their hearts to sexual impurity the degrading of their bodies with one another." "26Because of this God gave them over to sinful lusts..."

By the way, this close connction of God with evil would seem to lessen his aversion to it. (meaning, why does he punish us for sinning?) Good point. The justice aspect of God is kind of left out. But the emotional part stays. God is still jealous for us, and he still gets ticked off when we leave him. In this way the primary motivation to avoid sinning is not justice, it is Gods love.
Hm, this might be a good thing, eh? But I still don't like it much.

Hopefully there will be more about this soon.
