“The people who walked in darkness have seen a great light …” (v2). Isaiah prophesied that the Assyrians would attack Israel as the consequence for their rebellion against God. But Isaiah also saw a new day coming, when sin’s darkness would be overcome by God’s light. “For to us a child is born, to us a son is given; and the government shall be upon his shoulder, and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace” (v6).
Jesus, the Prince of Peace, brought light into the “deep darkness” of our world (v2), calling us to abandon sin and, by faith in Him, become part of His righteous, everlasting kingdom (v7).
