If you read the bible it shows God arguing with Satan over Job. God allowed some evil but used it for good. He did not create evil, Satan rebelled and that was evil. We have free will and are willing to be evil. This free will is so we can choose. I know my bible so I know what Im talking about.
God is Good.
Proverbs 16-16"How much better to get wisdom than gold, to choose understanding rather than silver!"
Choose understanding and read your bible!
