Nowhere to run; nowhere to hide. Describing John in Chapter 3, Luke writes:
A voice of one calling in the desert,
'Prepare the way for the Lord,
make straight paths for him.
Every valley shall be filled in,
every mountain and hill made low.
The crooked roads shall become straight,
And all mankind will see God's salvation.'
Here is a description of the topography of the Messiah's coming. There will be flatlands. Like the desert in Gulf War 1 - no impediment to the power of the US armed forces, a broad table on which the Revolutionary Guard is flanked and destroyed. No impediment to the projection of God's power, no obstruction to his line of sight. No crevices or hidden valleys where one can lay low to avoid his judgment. Or his mercy. A great image.
