Isaiah’s message (40:1-11) continues into Mark 1:1-8. God instructs his angels to comfort his people, to reassure Jerusalem that her punishment will soon be over. A voice from God’s angelic council urges fellow angels to build a highway from Babylon to Jerusalem so that the exiles may return home. John's cry for repentance is a voice crying in the wilderness of the mission to all nations, that a highway has been made to return to God. What should be the content of that preaching? Everything in this world is transitory and erratic but our God's promises are sure. The bringer of good news is to cry out, announcing God's triumphant return, like a warrior returning with power, bringing a reward with him. He gathers the little lambs of his flock into his arms and gently leads nursing sheep.
