He made a snake talk to people.
Nah! The snake was a tool of Satan
He killed bunches of first born sons to punish somebody else.
That he did. Considering the circumstances, I understand that. Long answer available.
He wreaked all kinds of destruction on Job's life and family, to make a point.
Nah! That was Satan again.
Where's the logic in anything else he/it does?
I'll have to resort to that pesky Bible again. The everyday affairs of the world have been in the hands of Satan since the rebellion in Eden. If that were not true, He would not have been able to offer them in Luke 4: 5-8. More pesky citations available for those interested.
