The only reason why God objected to sorcery is because the act created a bond between the human and the attentive rebel spirit. A person who joins with one of these gets a buddy for life, one that follows them around wherever they go. Imagine a rebel angel floating into the camp of Israel with the Tabernacle in site. That would tick God off. These rovers are bored to death and need something to do to pass the time. It seems there are rules of engagement and they can't interact with humans unless we draw close to them.
When Jesus was accused of expelling demons by the power of the devil he said that was ludicrous because a house divided against itself cannot stand. In other words Satan would not remove his fellow comrades from humans to make God look good. If a voice in your head tells you to do a selfless act to help someone else and it works then probably it was from God or it was just your conscience. If your interaction with the situation was a million to one odd then most likely it was from God. I can't imagine Satan ever involving himself with aiding humans unless it benefited him in the end. Unless your in the camp that believes Satan is really trying to make this world a good place without God. If Satan could resurrect a person would he? If he could he would most likely bring back someone who served him well or even a hot lady he fancied. He might even kill a serial killer if he had the power to do so.
The amazing magic and miracles of ancient times are a thing of the past. It seems their powers today are limited to coincidence and causality, both for God and Satan. No energy to matter conversion allowed! No new limbs can be miraculously produced by Benny Hinn's side show.
Or else this is just fantasy and myth and no need to worry.
