49:6 light to the Gentiles: The Servant fulfills the call of Abraham (Gen. 12:1–3) and the nation of Israel (Ex. 19:5, 6) to be a blessing to other nations. After Jesus’ death and resurrection, the great commission of global evangelism is carried on by His apostles (Acts 13:47; 26:23) and those who succeed them to the end of the age (Matt. 28:18–20).
49:6 raise up the tribes of Jacob … My salvation may reach to the end of the earth. The Servant’s goal is the salvation and restoration of Israel for the fulfillment of the covenant promise. But not limited to Israel, He is to function as a light bringing salvation to the Gentiles. Israel’s mission had always been to bring the nations to God (19:24; 42:6). This she will finally do very effectively in the tribulation after the conversion of the 144,000 witnesses (Rev 7:1–10; 14:1–5) and when she is restored to her Land at the Servant’s return to earth. Cf. 9:2; 11:10; 42:6; 45:22; Lk 2:32. Paul applied this verse to his ministry to the Gentiles on his first missionary journey (Ac 13:47).
49:6 It is trivial for you to be The Servant announced His mission to Israel in v. 5. Now, Yahweh reveals that the mission is not to Israel only, but to all the nations of the world. Redeeming Israel alone was too easy; Yahweh wishes for a greater display of His sovereignty.
a light to the nations Compare 42:6, where Israel may be given this mission to be a light to the nations (see note on 42:1–9). The mission that was Israel’s corporately is reassigned to the Servant individually, who fulfills Israel’s obligations to Yahweh in order to restore their relationship.
be my salvation to the end of the earth The entire world—not just Israel—will have access to Yahweh’s salvation through the Servant (see Acts 13:47). Isaiah has elsewhere hinted that the nations would one day be included in the people of God (see Isa 2:2–4).
49:6 light for the nations. A second purpose of the Servant is to bring the gospel to the nations (Luke 2:32; Acts 13:47; 26:23). He fulfills the call of Abraham (Gen. 12:3; 22:18) and of Israel (Ex. 19:5, 6). Today the ascended Christ brings the gospel to the nations through His body, the church (Matt. 28:18–20; 1 Pet. 2:9, 10).
49:6 In another deeper sense the Servant of God and Israel are one, for Jesus came of Israel and is the glory of Israel.
49:6 The servant will do more than restore Israel to its former glory. He will serve as an agent of salvation to the nations, thus fulfilling the divine promise to Abraham that through his descendants God would be a blessing to “all the peoples on earth” (Gn 12:3). Paul and Barnabas quote these words in Ac 13:47.
