Quote in context (taken from the Wikipedia article):
Much critical attention has been paid to the question of theodicy in Aeschylus. For generations, scholars warred incessantly over 'the justice of Zeus,' unintentionally blurring it with a monotheism imported from Judeo-Christian thought. The playwright undoubtedly had religious concerns; for instance, Jacqueline de Romilly suggests that his treatment of time flows directly out of his belief in divine justice. But it would be an error to think of Aeschylus as sermonizing. His Zeus does not arrive at decisions which he then enacts in the mortal world; rather, human events are themselves an enactment of divine will.
