Isaiah 9:1-7 The Promised Son And His Kingdom.
The ‘Nevertheless’ that begins this chapter refers to the covenant lawsuit against the nation as a whole, and nevertheless the hope which remains for the remnant, “who is distressed.” (v. 1) We now learn that this remnant will include the Gentiles, “by the way of the sea, beyond the Jordan, in Galilee.” (v. 1 Cf. Mt. 4:13-16) These would be translated from darkness and death to a shining great light (v. 2 Cf. Lk. 1:79; II Cor. 4:6; Eph. 5:8). However, though they would begin as a stump, the remnant would be multiplied, Jew and Gentile together as one people, and rejoice together with joy (v. 3 Cf. 66:14). The LORD would break the yoke of burden and deliver them from the warrior and oppressor (vv. 4-5 Cf. 66:15). The great shining light would be the Son, upon whom the government of the earth would rest.
“And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace.” (v. 6 Cf. 7:14; Lk. 2:7-11; I Jn. 4:9) “The four royal names express His divine and human qualities, giving assurance that He is indeed “Immanuel” (7:14).” (NGSB, p. 1038) So from Isaiah anyone would then know, that this One to come would be a Son, but He would also be God. The Son would come to fulfill the covenant promises culminating in the last of the old covenant administrations of grace-the Davidic. Furthermore, “of the increase of His government and peace there shall be no end (v. 7a Cf. Dan. 2:44; Lk. 1:32-33; Jn. 7:42). It would be a kingdom of the rule of the law-“with judgment and justice from that time forward, even forever. The zeal of the Lord of hosts will perform this.” (v. 7b Cf. 37:32)
