Meaning
Instruction by parables has been in use from the earliest times. A large portion of our Lord's public teaching consisted of parables. He himself explains his reasons for this in his answer to the inquiry of the disciples, "Why speakest thou to them in parables?" (Matt 13:13-15; Mark 4:11, 12; Luke 8:9, 10). He followed in so doing the rule of the divine procedures, as recorded in Matt 13:13.
The parables uttered by our Lord are all recorded in the synoptical (i.e., the first three) Gospels. The fourth Gospel contains no parable properly so called, although the illustration of the good shepherd (John 1:10-16) has all the essential features of a parable. (See List of Parables in Appendix)
