We are judged by God. We are punished or rewarded. For this reason, all religions believe that the world was created as a test, but the world is far too unfair to be a test. God could have designed a much better test. Life is a journey. The world was created so that God could go with us on this journey. God feels what we feel. By knowing sorrow and loneliness through us, God knows what love is.
God created angels, demons, and humans, outside of Himself, allowing them to cause suffering. Satan became evil, and Satan hates God, but Satan can do no harm to God. God loves the humans, so Satan destroys the humans by causing them to violate the Law of God. This is how God has humans who go on a journey of good and evil. Satan does exactly what God expected, but Satan is not stupid. He keeps his hatred of God to himself. He stays within the Law of God, and he is still in Heaven.
Jesus is at the “Right Hand” of God which transcends Heaven. When God looked away from the crucifixion, the devil openly cursed God. To this day, the devil does not know that Jesus transcends Heaven and is a witness against him. This could not be revealed until the time of the end because this revelation causes the end. This revelation causes the war (debate) between Satan and Michael.
