I don't understand Job. Why did God allow Satan to toy with His good & faithful servant?

Satan is no animal spirit. He was created as we all were in the first earth age and was so good he worked his way up to be a cherub, a protector of the Mercy Seat, then got a big head and fell taking a third of God's children with him. That is why we are here in a flesh body, to decide who you will serve, God or Satan. I choose God and pray that all will.
