“You who bring good news to Zion, go up on a high mountain … lift up your voice with a shout … say to the towns of Judah, "Here is your God!" (v9). Isaiah prophesied that God would send His Messiah to comfort His suffering people (v1). God’s arrival in the Messiah would be “with power … with a mighty arm,” with reward and recompense. Yet the conquering King would also “tend his flock like a shepherd: He gathers the lambs in his arms and carries them close to his heart” (v11).
“Have you not heard?” (v28). All people need to hear the good news that Jesus the Messiah has brought God’s salvation in power and gentleness, justice and love.
