Last week I was reading Isaiah 46:1-7 where God is speaking about the idols of Babylon and how powerless they are. Along with the passage, I was also reading John N. Oswalt's commentary The Book of Isaiah. His note on verses 5-7 caught my eye:
...Isaiah is not denying that the deity could be more than the idol. He is simply saying that once a deity is associated with an idol, then it is impossible for that deity to be genuinely independent of creation. The continuity with creation defines the deity's identity and forges its limitations. It cannot be independent from history and cannot, therefore, deliver from history (p. 231).
