As always, God wont do anything. Maybe Amara frees Sam, but I think Rowena simply opens the cage on Dean's order, even if Lucifer will be freed as well. On the other hand, maybe Lucifer apported Rowena and Crowley also in the cage from what we saw in the promo, I might think it's Lucifer's reality warping inside the cage.
