Jesus seems to have it in for fruitless fig trees and mountains!  What's so bad about them that the one would deserve a curse and the other to be tossed into the ocean?  Given the wider context, this doesn't seem to be simply a landscaper's rant.  These are warnings to each and every one of us who claims faith in Christ.  But there's also an incredible power and responsibility entrusted to us! From Matthew 21:18-22.
