237. Another figure has become almost identified with the name of Jesus,--such abundant and incomparable use did he make of it. Parable was, however, no invention of his, for the rabbis of his own and later times, as well as the sages and prophets who went before them, made use of it. As distinguished from other forms of illustration, the parable is a picture true to actual human life, used to enforce a religious truth. The picture may be drawn in detail, as in the story of the Lost Son (Luke xv. 11-32), or it may be the concisest narration possible, as in the parable of the Leaven (Matt. xiii. 33); but it always retains its character as a narrative true to human experience. It is this that gives parable the peculiar value it has for religious teaching, since it brings unfamiliar truth close home to every-day life. Like all the illustrations used by Jesus, the parable was ordinarily chosen as a means of making clear the spiritual truth which he was presenting. Illustration never finds place as mere ornament in his addresses. His parables, however, were sometimes used to baffle the unteachable and critical. Such was the case on the occasion in Jesus' life when attention is first called in the gospels to this mode of teaching (Mark iv. 1-34). The parable of the Sower would mean little to hearers who held the crude and material ideas of the kingdom which prevailed among Jesus' contemporaries. It was used as an invitation to consider a great truth, and for teachable disciples was full of suggestion and meaning; while for the critical curiosity of unfriendly hearers it was only a pointless story,--a means adopted by Jesus to save his pearls from being trampled under foot, and perhaps also to prevent too early a decision against him on the part of his opponents.
