I would advise any young Christians who are considering a career in government, irrespective of branch, at any level, from low to high, that before any other study they read the first six chapters of the Book of Daniel: Thoughtfully, very carefully, and in the context of the Exile.
Mutatis mutandis, of course: Making the necessary changes. Paganism is not the same as neo-paganism; the times before Christ were not the same as the times after. And the literary genre of the book is strange and difficult for us. But the times for which it was written are very like the ones we are in.
