4:12-17 It is just with God to take the gospel and the means of grace, from those that slight them and thrust them away. Christ will not stay long where he is not welcome. Those who are without Christ, are in the dark. They were sitting in this condition, a contented posture; they chose it rather than light; they were willingly ignorant. When the gospel comes, light comes; when it comes to any place, when it comes to any soul, it makes day there. Light discovers and directs; so does the gospel. The doctrine of repentance is right gospel doctrine. Not only the austere John Baptist, but the gracious Jesus, preached repentance. There is still the same reason to do so. The kingdom of heaven was not reckoned to be fully come, till the pouring out of the Holy Spirit after Christ's ascension.

16. The people which sat in darkness saw great light; and to them which sat in the region and shadow of death light is sprung up—The prophetic strain to which these words belong commences with the seventh chapter of Isaiah, to which the sixth chapter is introductory, and goes down to the end of the twelfth chapter, which hymns the spirit of that whole strain of prophecy. It belongs to the reign of Ahaz and turns upon the combined efforts of the two neighboring kingdoms of Syria and Israel to crush Judah. In these critical circumstances Judah and her king were, by their ungodliness, provoking the Lord to sell them into the hands of their enemies. What, then, is the burden of this prophetic strain, on to the passage here quoted? First, Judah shall not, cannot perish, because Immanuel, the Virgin's Son, is to come forth from his loins. Next, one of the invaders shall soon perish, and the kingdoms of neither be enlarged. Further, while the Lord will be the Sanctuary of such as confide in these promises and await their fulfilment, He will drive to confusion, darkness, and despair the vast multitude of the nation who despised His oracles, and, in their anxiety and distress, betook themselves to the lying oracles of the heathen. This carries us down to the end of the eighth chapter. At the opening of the ninth chapter a sudden light is seen breaking in upon one particular part of the country, the part which was to suffer most in these wars and devastations—"the land of Zebulun, and the land of Naphtali, the way of the sea, beyond Jordan, Galilee and the Gentiles." The rest of the prophecy stretches over both the Assyrian and the Chaldean captivities and terminates in the glorious Messianic prophecy of the eleventh chapter and the choral hymn of the twelfth chapter. Well, this is the point seized on by our Evangelist. By Messiah's taking up His abode in those very regions of Galilee, and shedding His glorious light upon them, this prediction, He says, of the Evangelical prophet was now fulfilled; and if it was not thus fulfilled, we may confidently affirm it was not fulfilled in any age of the Jewish ceremony, and has received no fulfilment at all. Even the most rationalistic critics have difficulty in explaining it in any other way.
