Thesis 63: Christ’s Ascension to the Throne of David
It is a sin to form "the State." Deuteronomy 17:14 does not contradict this, and this is where most of the expositors' mistakes originate. Example: Deuteronomy 31:16, though part of "the Law," is prophecy, obviously. Deuteronomy 17:14 is also prophecy, though perhaps not as obviously. It is not a command. It speaks of sin, ordained but not approved by God. Perhaps instead of arguing over labels ("prophecy" vs. "law") for Deuteronomy 17:14, we should acknowledge a third category, which we might call "witness" (Deuteronomy 30:19; 31:19; 31:21,26,28). Deuteronomy 17:14 is not a command to have a king, and not solely a prophecy, but a future witness against Israel.
