What the Bible says about Christ as a Light to the Gentiles
(From Forerunner Commentary)
Christ would eventually serve as a light to the Gentiles. While Simeon does not quote Isaiah directly, he was certainly familiar with Isaiah 49 as well as Isaiah 8 and 9.
In these two early chapters of Isaiah, the prophet also shows Christ as a light to the Gentiles. Lurking in them is the rhetoric of Joel—the darkness, the shadow of death, yet afterward, just as in Joel, hope shines through.
