But they have the best King possible, something this world won't have until the Second Coming.
“...they have the best King possible...”
Absolutely - excellent point - and ohe that I meant to be inherently understood ...
In the fallen world here, our forms of government will always be flawed, but we can certainly try. Power corrupts those at the top who hold the power due to our fallen nature; whether the power holder is a king, an Obama, etc.
The fact that heaven is a hierarchy suggests that a monarchy here (on earth) could work, but only insofar as the monarch can keep his or her tendency to the capital sins at bay in imitation of Christ the King. In other words, it is not the monarchy concept in and of itself that is off, any human in power can and eventually will be corrupted (look at Obama!) unless they are consciously and deliberately imitating Christ.
