because God needs Satan. Satan is not some incredibly evil entity like christfags are led to believe. If God is the 'Judge' then Satan is like the prosecutor. He brings forth evidence as to why we deserve to go to prison (Hell), showing evidence of our past sins. Jesus would be like our Attorney, defending us and trying to convince the judge (god) why we deserve to go to Heaven.

Without the three, there could be no balance. God is not as all powerful as people claim him to be either. People like to think of God as this being who can do literally anything at any time, but he isn't. He is the forger of this universe, and he has a limited amount of control over it. He can't just warp reality though. Once the marble is cut, it cannot be uncut.
