Who is the battle between, and what is it a battle over?
Let's get back to this.
Love and greed. It's a battle for the service of all mankind. Does a man choose to sacrifice himself for the greater good, or serve only his own desires?
I'm pretty much in agreement with this. Let's see if I can expand it a bit more wrt Satan's role.
The battle is between, on the overarching level, Good and Evil.
Good is that which sets free, that which offers itself for the sake of others, that which has love and fellow-feeling/sympathy/etc, and that which forgives to make room for a new life. Good is represented by those who do the above and call other people to do so.
Evil is that which enslaves, that which harms others for its own benefit, that which does not prefer that another person be happy to that he be sad. Evil is represented by Satan and everyone he influences to do evil.
What Satan does is to disguise evil and make good seem unfeasible. E.g. "You'd die if you gave away all your possessions to the poor, and you'd be no help to anyone then, and they'd waste it. No point in doing that." accompanied by "You have to look out for yourself. It's a dangerous world filled with evil. Better make sure you're in a position of strength." and the like. I could go on for pages, I'm sure.
The battle is, as puglover says, for the service of mankind, ie for their immortal souls. Satan is weaker than God, so cannot attempt to win humans either by force or by giving them a better deal. In the manner described above, he tries to convince people to reject God of their own free will, something God allowed humans to have when He created us in His image as so that we would be creations of inherent worth rather than toys.
God says: "You have sinned. I cannot stand sin. Let me send my Son to wash away your sin." This has the qualities described of Good above - offering for the sake of others (this derails into a discussion of the Trinity), setting free from sin, forgiveness.
Satan says either this: "You're not good enough. You couldn't stand it. You've sinned so much, you'd die if you went near God. You don't belong in Heaven." (
IMO, here's a case of this.) That's one extreme.
Or this: "You've done more good things than bad things. You shouldn't need Jesus, and he doesn't exist anyway. That's for pathetic, weak people. If God exists, surely he'll let you into Heaven on your own merit." That's the other extreme.
