John Ballenger of Baltimore (Woodbrook Baptist Church) writes in Clergy Journal the following good point:
The parable offers the opposite advice from the adventure movie line, "Kill them all, let God sort them out." Jesus in effect says, "Care for them all, let God sort them out." In forbidding the servants to root out the weeds, the householder, in effect, commands that the weeds receive the same care as the wheat until the day of harvest.In that case the farmers are responsible for tending and God is responsible for the final result. I am struck by the willingness to let the good wheat and the weeds share the precious water and nutrients of the soil. I guess if we are thinking we're wheat, we're not so special after all, but as in so many parables, if we are the weeds, we have much for which to be grateful.
My husband always says, "a weed is just a plant or even flower, growing in the wrong place."
Looking at responsibility, and accepting that God has the ultimate responsibility, perhaps ours is to recognize the flower mistaken as a 'weed' and share this space with a different crop. Then when all is said and done, ultimately that is, God will do any necessary sorting.
