^^^ God makes people alive. God lets people die. God does everything. When people come to life or die, God does it, just like He rolls the stars around, runs the electric-plasma engines that make the stars shine, makes the earthquakes and the peace that follows. The whole thing is His, He makes it all happen in every way, and understanding how and why He does things is what counts.
Satan can't do anything. Rather, (in this universe, at least) Satan requests from God, and God is the Mover Who does it. Why? Because nothing in this universe happens without God doing it.
Why does God answer requests to do bad things? Because when He set up this universe, He set it up on a request basis, that He would answer requests. There wasn't any idea of death or evil with God. But even though Satan - and to a lesser extent, people - brought evil into being, God doesn't change His answering of requests.
The interesting part about this is, God has His own plan that will get rid of all the evil. He will do it by creating the Lake of Fire, and dissolving the whole universe in it... including Satan, his angel followers, and all his human followers, as well. Why will He do this to those people and fallen angels? Because they are asking for God to not be in their presence. The LoF crash will be the result of God leaving this universe at their request.
God owns it; He has the right and duty. He, also, offers everyone a way out... Jesus salvation. Even believers die in this life. And God does it for them, so that they can put off the evil, and take up their places in heavenly joy... with a new body that doesn't have any of the weakness of this one.
So sad that you are going to miss it by asking God not to be in your life. But, God does it for you, whatever it is that you ask. You just don't realize all the things that you are really asking when you ask something. For example. If you are like
af_newbie, and ask God to write something in this forum, you are really saying down deep that you want God to NOT write anything in this forum, especially when you request Him to, because you don't want to be forced into accepting the reality of God. (Why do I waste my time on you?)
You are like the quadriplegic who feels so helpless that he wants to die. But he is so weak that he can't take his own life. So he says, "Let me die; I can't take any more of this," not knowing that it is God he is requesting his death from. For a long time God withholds death, trying to get the guy to ask to be saved. And it actually stresses God to stretch His "disobedience" of His own law of giving what was asked for (The stretching is what pained the soul of Jesus, to death, on the cross).
But finally God gives the quadriplegic joker what he asks for. Too bad the QJ didn't realize that there was a lot more to the rejection of God than the simple "blankness" he was asking for. God tried to warn him over and over... even prepared a way (Jesus salvation) to get him out of his illness and into a new body in joy and happiness, forever.
But even the blankness of complete reduction to nothingness will be accomplished in the QJ. It will all be done at the end of eternity.
