How could Satan be cursed to crawl on the ground, yet walk before God in Job? In Genesis 3:1 we find a serpent. Supposedly Satan inhabited the serpent, or the word should be translated Shining One (NIV). At any rate, God curses the snake in 3:14: "On your belly you shall go, and  you shall eat dust all the days of your life."

If going on his belly is Satan's fate, then how is he coming and going before God in Job 1 and 2, and on the earth, "walking back and forth on it" instead of crawling around? 

The only reconciliation I can think of is that the serpents were different back then, not relegated to their bellies as they are now -- so the curse is directed to the animal and not Satan. 

I welcome answers from any Christian viewpoint that accepts the Genesis 1 days of 24 hours and a literal rendering of Genesis 1-11 events, and believes in the Apostle's Creed.
I guess when you consider that Revelation clearly identifies the serpent in the garden as Satan, then this might appear to be a problem. However when you consider that Satan is a spiritual being that according to scripture can "enter" people, as well as Romans 16:20:


  The God of peace will soon crush Satan under your feet.


Then it seems that there would be a dual fulfillment of this prophetic curse pronounced against "the serpent": one enacted immediately against the creature that Satan possessed (you are not alone in thinking that its form must have been transformed at this point); a second still to be fulfilled as per this verse acting on Satan himself. 

The narrative in Job lies between the initial fulfillment in Genesis and the final fulfillment reaffirmed in Romans.
