Some people say that, Christian theology is like this: 1. Use God to explain the problems when God is able to explain. 2. When God is not able to explain, use Satan to explain. So, the solution to many difficult problems is just God + Satan. The formula is: Solution = God + Satan.
To paraphrase from The Matrix, do not try to rationalize the actions attributed to God. That is impossible. Instead, try to understand the truth. There is no God.
Since (according to the mythology) the omnipotent and omniscient God created Satan, it's still God's doing.
Satan is no rebel! Another brother. High holy true Satan! I don't care for the bible, but the name Satan belongs to someone. Rebellion is weak beyond the soil. Satan is the man. Tempt. Adversary, he ain't. The angel who flew away with hell, Tempt. Maybe I can unearth something he left behind. I am sure he had a hand in writing the KJV.
God vs Satan means Good vs Evil. Yes, it is too simple, in this world, you can either label things with good or bad (evil), everything good -------praise God everything bad ---------- blame Satan.
