Definition of Parable:
Parable signifies in general a comparison, or a parallel, by which one thing is used to illustrate another. It is a likeness taken from the sphere of real, or sensible, or earthly incidents, in order to convey an ideal, or spiritual, or heavenly meaning. As uttering one thing and signifying something else, it is in the nature of a riddle and has therefore a light and a dark side, it is intended to stir curiosity and calls for intelligence in the listener. The derivation of the Hebrew is unknown.
Parable of the Doctor and the Sick
Luke 5:27-32 (Matthew 9:12; Mark 2:17)
After this he went out, and saw a tax collector, named Levi, sitting at the tax office; and he said to him, "Follow me." And he left everything, and rose and followed him. And Levi made him a great feast in his house; and there was a large company of tax collectors and others sitting at table with them. And the Pharisees and their scribes murmured against his disciples, saying, "Why do you eat and drink with tax collectors and sinners?" And Jesus answered them, "Those who are well have no need of a physician, but those who are sick; I have not come to call the righteous, but sinners to repentance."
People in Palestine were divided into roughly two groups: the orthodox Jews who rigidly kept the law and all its petty regulations, and the rest who didn't keep all the minute regulations. The orthodox treated the latter like second class citizens. They scrupulously avoided their company, refused to do business with them, refused to give or receive anything from them, refused to intermarry, and avoided any form of entertainment with them, including table fellowship. Jesus' association with the latter, especially with tax collectors and sinners, shocked the sensibilities of these orthodox Jews. In calling Matthew to be one of his disciples, Jesus picked one of the unlikeliest of men -- a tax collector who by profession was despised by the Jewish people. When the Pharisees challenged his unorthodox behavior in eating with public sinners, Jesus' defence was quite simple. A doctor doesn't need to visit healthy people; instead he goes to those who are sick. Jesus likewise sought out those in the greatest need. A true physician seeks healing of the whole person -- body, mind, and spirit. Jesus came as the divine physician and good shepherd to care for his people and to restore them to wholeness of life. The orthodox were so preoccupied with their own practice of religion that they neglected to help the very people who needed the greatest care. Their religion was selfish because they didn't want to have anything to do with people not like themselves. Jesus stated his mission in unequivocal terms: I came not to call the righteous, but to call sinners. Ironically the orthodox were as needy as those they despised. All have sinned and fall short of the glory of God (Rom show them mercy and kindness?
