The first two chapters of Luke are in spirit really a bit of the Old Testament continued to the very threshold of the New. These chapters contain the poetry of the New Testament, which has taken deep hold of the heart and fancy of the Church.
In this section of his Gospel, Luke shows himself to be a genuine historian. A biographer is not satisfied with narrating the public life of his hero, but prefaces to his work some account of the family, and of the birth and childhood. So our understanding of the ministry of Jesus becomes far deeper when we know that he grew up among the simple, devout folk who are described in the first two chapters of Luke. The picture of Mary in these chapters, painted with an exquisite delicacy of touch, throws a flood of light upon the earthly life of the Son of Man.
Beauty of detail, however, must not be allowed to obscure the central fact. The culmination of the narrative, undoubtedly, is to be found in the stupendous mystery of Luke 1:34,35. Far from being an excrescence in the narrative, as it has sometimes been represented in an age of rampant naturalism, the supernatural conception of Jesus is the very keystone of the arch. In this central fact, Matthew and Luke, totally independent as they are, are perfectly agreed. By this fact Jesus is represented, more clearly perhaps than by anything else, as not a product of the world but a Saviour come from without.
=(2) The Prodigal Son.=--The parable of the Prodigal Son, simple though it is, has often been sadly misinterpreted. It has been thought to mean, for example, that God pardons sin on the basis simply of human repentance without the necessity of the divine sacrifice. All such interpretations are wide of the mark. The parable is not meant to teach how God pardons sin, but only the fact that he does pardon it with joy, and that we ought to share in his joy.
Misinterpretation of the parable has come from the ignoring of its occasion. The key to the interpretation is given in Luke 15:1,2. Jesus was receiving publicans and sinners. Instead of rejoicing at the salvation of these poor, degraded sons of Abraham, the Pharisees murmured. In rebuke, Jesus spoke three parables. One of them, the parable of the Lost Sheep, is reported also by Matthew, ch. 18:12-14; but the last two, the parables of the Lost Coin and of the Prodigal Son, appear only in Luke.
