But think about it more. When Adam and Eve were told that they could eat of every tree but one, didn't they choose to listen to the god of this world over the God of heaven ?
Their test was a tree. Does the God of heaven have a day? does the god of this world have a day?
Now my point is that the day we have esteem for shows which god we choose.
I don't think Paul is saying "just pick one, whatever". I think he means to "get it right in your mind"
