Now, I've written about this before, and reasonable people everywhere gave wonderful, reasonable explanations for these verses and explained them well. In my head, I understand perfectly well what these verses are saying and that they are, in fact, quite beautiful. Unfortunately, cold, hard logic cannot keep me from cringing at the words.
"Let every valley be filled in"
And "every mountain and hill laid low"
"Let every cliff become a plain,
and the ridges a valley"*
Yes, yes. I understand that we are talking about preparing a way for the Lord and removing any obstacles that stand in the way of that. I agree that the meaning of the words is beautiful. Still, if you wish to reason with me about all of that, you might as well save yourself the time and trouble. The idea of leveling the mountains will still strike enough horror into me to recycle this post every time I hear them.
*Note also the inconsistency of this; if the valleys are going to be filled in, then why are we turning the ridges into valleys? Why not keep the valleys we have?
