Seems to me that we must exert our imaginations about one aspect of the parable of the Lost Sheep in order to grasp the parable’s full significance.
The aspect I have in mind is the extreme contrast between the state in which the 99 sheep find themselves and the state of the one little lost sheep.
To a statistician or an economist, the parable might not make any sense at all. “Wait a minute. 99 on one side. One on the other. Take the 99 to the bank and be done with it.”
