There may be something in this parable that helps us in introspection as well. Maybe it could help us survey our inner landscape and evaluate the weeds among the wheat that perhaps need pruning, but not plucking up. That might mean that you and I ought to berate ourselves a little less harshly for our flaws and faults. Because, while there aspects of our personality that shouldn't be allowed to take over the whole field, they may just contribute to our life's harvest and our contribution to the world.
And since we know that we often tend to judge others for qualities we dislike in ourselves, it's something worth thinking about.
