Read the book and then you'll understand
We always seem to think Satan is very intelligent, but I'm convinced George W. Bush is Satan. So, what if Satan is actually an idiot? Doesn't that make more sense? Would a really bright Angel get kicked out of Heaven?
(I don't actually believe any of that religious crap. I'm just funnin'!)
God is on top and Satan is at the bottom. Good always win over evil.
There is no IF Satan is deceptive, and God will never tempt us.
Good gives life options while evil takes them away. God offers options while Satan takes them away.
You might consider calling a church to get the best answer to this question. They are there every day.
That's one of the big risks.
