Matthew 13:10

ἐν παραβολαῖς. The parable is suited (1) to the uninstructed, as being attractive in form and as revealing spiritual truth exactly in proportion to the capacity of the hearer; and (2) to the divinely wise as wrapping up a secret which he can penetrate by his spiritual insight. In this it resembles the Platonic myth; it was the form in which many philosophers clothed their deepest thoughts. (3) It fulfils the condition of all true knowledge. He alone who seeks finds. In relation to Nature, Art, God Himself, it may be said the dull ‘seeing see not.’ The commonest and most obvious things hide the greatest truths. (4) The divine Wisdom has been justified in respect to this mode of teaching. The parables have struck deep into the thought and language of men (not of Christians only), as no other teaching could have done; in proof of which it is sufficient to name such words and expressions as ‘talents,’ ‘dispensation,’ ‘leaven,’ ‘prodigal son,’ ‘light under a bushel,’ ‘building on sand.’
