"The parables of the New Testament are here treated historically. It is insufficient to extract from each separately its own particular lesson or lessons. The public career of our Lord was marked by progress in both its events and His teaching. The instruction He imparted presents two governing features. First, He taught according to the capacity of the hearers. As they grasped the instruction further truth was unfolded. Second, as opposition developed in intensity so did His parables in force and solemnity."
"Each parable therefore reflects the conditions which called it forth and is illuminated by the circumstances. In consequence they must study be studied consecutively if the full sense and force of each is to be realized. This applies to the parables in the Epistles also."
