“The people who walked in darkness have seen a great light; those who dwelt in a land of deep darkness, on them has light shone.” Isaiah 9:2
The Scripture’s great contrast between light and darkness is here on display through the words of the prophet Isaiah concerning, in the near, hope in the midst of the Assyrian invasion, yet in the far, a future greater in hope found in the person of our Lord Jesus Christ. In the context of Isaiah’s prophecy, which like so much of Old Testament prophecy looks toward the future and sees an amalgamation of events (often called prophetic perspective) this prophecy is set in the midst of the coming judgment on Israel as God-ordained punishment for their apostasy from God. The darkness expresses the hopelessness of the current situation, yet the language of Isaiah, “…have seen a great light” is that of the prophetic perfect, used to express the surety of a future event as though it has already happened. Commenting on this passage Calvin writes,
“He speaks of future events in the past tense, and thus brings them before the immediate view of the people, that in the destruction of the city, in their captivity, and in what appeared to be their utter destruction, they may behold the light of God. It may therefore be summed up in this manner: “Even in darkness, nay, in death itself, there is nevertheless good ground of hope; for the power of God is sufficient to restore life to his people, when they appear to be already dead.”
Certainly, a restoration from the hands of Israel’s captors is in view, yet we must not limit our understanding of this prophecy to the events surrounding Israel and Assyria, particularly since this passage is referenced elsewhere.
Written under the inspiration of the Holy Spirit, the Gospel of Matthew 4:15-16 cites this passage from Isaiah 9 in the context of Jesus beginning His earthly ministry
“12 Now when he heard that John had been arrested, he withdrew into Galilee. 13 And leaving Nazareth he went and lived in Capernaum by the sea, in the territory of Zebulun and Naphtali, 14 so that what was spoken by the prophet Isaiah might be fulfilled: 15 “The land of Zebulun and the land of Naphtali, the way of the sea, beyond the Jordan, Galilee of the Gentiles— 16 the people dwelling in darkness have seen a great light, and for those dwelling in the region and shadow of death, on them a light has dawned.” 17 From that time Jesus began to preach, saying, “Repent, for the kingdom of heaven is at hand.” Matthew 4:12-17
This further illumination by the Spirit of God, the Divine Author of Scripture, aids in our understanding of the fullness or fulfillment of the prophecy found in Isaiah, namely that found in the person and work of Jesus Christ as the great light that offers hope in the midst of a darkened world. Turning again to Calvin we read,
“If, therefore, we wish to ascertain the true meaning of this passage, we must bring to our recollection what has been already stated, that the Prophet, when he speaks of bringing back the people from Babylon, does not look to a single age, but includes all the rest, till Christ came and brought the most complete deliverance to his people. The deliverance from Babylon was but a prelude to the restoration of the Church, and was intended to last, not for a few years only, but till Christ should come and bring true salvation, not only to their bodies, but likewise to their souls.”
Christ Himself makes this connection in John 8:12 when He states,
“I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.”
In John’s Gospel, this statement is buttressed with the truths about Christ being the Light from chapter 1, verses4-5, 9 and chapter 3:19-21. Our Lord’s declaration that He is light has profound biblical meaning. Primarily, it asserts His deity bringing to mind such Old Testament declarations such as Exodus 13:21, where the pillar of fire led the way for the Israelites in the wilderness; Psalm 27:1 “The LORD is my light and my salvation; whom shall I fear”; Micah 7:8; Isaiah 60:20; as well as 1 John 1:5. The declaration of light is a declaration of purity and holiness, in which there is no shadow or defect (James 1:17). Additionally, several Old Testament passages assert that God’s Word is light (Ps. 119:105; Prov. 6:23) adding to the profundity of John 1:1.
Secondarily, by stating He is light, Christ assumes the role that God had intended for Israel to occupy as a city on a hill whose light was to shine forth to the world, yet because of their disobedience failed to properly fulfill the mission of God. Therefore, God has appointed His True Servant Israel, His Son, to go forth as a light unto the nations bringing salvation to the ends of the world. Isaiah 42:6; 49:6
This advent season, may our eyes be drawn to the Light of the world. May we realize that He alone can shine forth in a world of darkness. This Light alone possesses the light of life. Walking in spiritual darkness, dead in our trespasses and sins is a hopeless and dire situation that leaves us under the wrath of God and destined for the experience of His everlasting judgment. May we look toward the light, Our Lord Jesus Christ, and see Him as our only hope. Surety in a world of darkness and a beacon for all who come to Him in repentance and faith.
