I glanced at it, but I wasn't sure why you brought up that scripture, and then I replied to another post.
But I'll reply to it now.
You said:
"God created Satan. Jesus said a good tree cannot produce bad fruit. Is God a good tree?
Matthew 7:17-18
17 Even so every good tree bringeth forth good. fruit; but a corrupt tree bringeth forth evil fruit. 18 A good tree cannot bring forth evil fruit, neither. can a corrupt tree bring forth good fruit."
^ The mistake you're making here is assuming that God created satan in the way satan is now (evil.) According to the bible, satan fell from grace, so in the beginning satan was created as an angel, with free will. And satan chose to rebel against God.
So you are misapplying that Matthew passage about good fruit. Of course God is a good tree, it's created beings who make the decision to go their own way, and end up choosing evil over good. I still don't know why you would even bring up that passage, are you implying that satan is good because God created satan?
