In the first few words of B’resheet, we are given our first glimpse of Messiah; even the Jewish sages agree upon this. When haShem spoke the universe into being, his first recorded words were, “Let there be light.”
Even Talmudic sources agree that this is a reference to the Messiah. While Adonai was indeed speaking creation into existence, he was also speaking prophetically about Messiah, who is often referred to as the Light of the world.
While messianic Judaism and mainstream Judaism differs on the point of who the Messiah was or is, there is unity in interpreting this passage as a messianic promise on behalf of haShem. One can be completely sober-minded (as opposed to a member of the wine of the month club) and find Messianic significance even here in the earliest passages of Scripture.
