The Parable of the Weeds

I've been thinking about Jesus' parable of the weeds planted in the field of wheat. It's often seen as a parable about final judgement. It's one of the few parables where Jesus explains its meaning to his disciples. But he doesn't really explain the meaning, he just points out what the images represents and He does indeed talk about a final judgement when "all causes of sin and all evildoers" will be thrown into a "furnace of fire."

But I don't want to talk about that! What interests me is the conversation between the servants and the Master. The servants offer to pull up the weeds. (Jesus later explains that the weeds are the "sons of the evil one.") But the Master says to the servants (I paraphrase), "No, don't pull them up. You might do more damage than good. I'll have my harvesters take care of that later. You don't have to worry about it."

Sometimes, too often, I see Christians trying to "pull up the weeds" themselves instead of letting God take care of it in His time and method. When we try to amend constitutions or pass laws to "pull up weeds" are we not assuming the role of the One who sowed the field, the One who has His own way dealing with the weeds? What "weeds" are you trying to pull up? How much damage will you do to the wheat in the process?
