How beautiful on the mountains
are the feet of those who bring good news,
who proclaim peace,
who bring good tidings,
who proclaim salvation,
who say to Zion,
“Your God reigns!”
Listen! Your watchmen lift up their voices;
together they shout for joy.
When the LORD returns to Zion,
they will see it with their own eyes.
Burst into songs of joy together,
you ruins of Jerusalem,
for the LORD has comforted his people,
he has redeemed Jerusalem.
The LORD will lay bare his holy arm
in the sight of all the nations,
and all the ends of the earth
will see the salvation of our God.
Let the word go out: Good news has come. Break forth with singing. Shout out for joy. Let there be loud rejoicing. Isaiah is speaking about the gospel, the good news, the glad tidings. This is the content, and cause for unrestrained celebration: Your God reigns!
Jerusalem was still in ruins and Israel in exile, but the prophet sees behind the veil and beholds God returning to Zion. Though everything seemed dark at present, Jerusalem would not be forgotten. The Lord would come to console his people, to redeem Jerusalem and set her free.
The consolation of Israel was what Simeon had been longing for that day in the temple when he saw Joseph and Mary bringing their newborn infant into the temple courts. He swept the Christ Child into his arms and thanked God: “Sovereign Lord, as you have promised, you may now dismiss your servant in peace. For my eyes have seen your salvation, which you have prepared in the sight of all nations: a light for revelation to the Gentiles, and the glory of your people Israel.” Then he blessed the baby Jesus: “This child is destined to cause the falling and rising of many in Israel, and to be a sign that will be spoken against, so that the thoughts of many hearts will be revealed.” (See Luke 2:25-35.)
The redemption of Jerusalem is what Anna had been watching for those many long years she spent fasting and praying in the temple. When she saw Simeon blessing Jesus, she immediately recognized what was happening: the fulfillment of Isaiah’s ancient prophecy was at hand. “Coming up to them at that very moment, she gave thanks to God and spoke about the child to all who were looking forward to the redemption of Jerusalem” (Luke 2:36-38).
This is the good news of “salvation.” The Hebrew word, which the prophet used twice in this passage, is yeshuah. When it is used as a personal name, it is Yeshua, which is translated into English as Jesus — his name means “salvation.”
Salvation is a person, for Jesus himself is the consolation of Israel and the redemption of Jerusalem. He is the good news of the gospel, the Lord who reigns, and he has returned to Zion. The New Testament speaks of the new Jerusalem, a Jerusalem that is free, a Jerusalem that is above, a heavenly Jerusalem that comes down, joining heaven to earth (Galatians 4:26; Hebrews 12:22; Revelation 21:2).
This new Jerusalem is the Church, which is identified as the body and bride of Christ. It is important, however, to understand that the Church in the New Testament is not a separate entity from Israel in the Old Testament. Indeed, the Church is Israel. What was promised to Israel in the Old Testament is received by Israel in the New, by all who come to Jesus the Messiah. Even the nations (the Gentiles) who receive him as King are, to use Paul’s words in Romans 11, “grafted into” the root, which is Israel.
The Lord Jesus has laid bare his holy arms at the cross, where he defeated the powers in the sight of all the nations. And all the earth will know his salvation.
A few years back, I wrote an Advent version of Psalm 122, in light of Isaiah 2, Isaiah 52, Revelation 21, the New Jerusalem and the coming of King Jesus into the world: Psalm 122 and the New Jerusalem.
