The extent to which the supplementing should be carried
From the preceding discussion it is clear not only that no important topic is ever completely presented, but also that there is scarcely any limit to the extent to which it may be supplemented. Men get new thoughts from the same Bible texts year after year, and even century after century. How far, then, should the supplementing be carried?
The maximum limit cannot be fixed, and there is no need of attempting it. But there is great need of knowing and keeping in mind the minimum limit; for in the pressure to hurry forward there is grave danger that even this limit will not be reached.
