I never did understand this parable, and now I know why. The caretaker of the field was told to let the weeds and the wheat grow TOGETHER until the harvest. I've had gardens, and I've never had one morsel of harvestable food survive an onslaught of weeds. Then I did a little farming research, and its a FACT that if you let weeds grow in a wheat field, they will kill the crop entirely and you will have nothing but weeds. I thought maybe I was the only one who experienced cognitive dissonance with this until I recently read a book called "The Gospel of Thomas, Annotated and Explained" by Stevan L. Davies, and he made the very same point.
