Behold, you shall call a nation that you do not know,
and a nation that did not know you shall run to you,
because of the Lord your God, and of the Holy One of Israel,
for he has glorified you.
Isaiah 55:5
Observation: Isaiah chapter 55 has two famous passages. The first is verses 1-2, that call everyone to come, drink of the Lord's water and eat of his bread with no money. The second is verses 8-9, when the Lord explains that his ways and his thoughts are higher than ours and beyond our understanding. Exactly in between those two is this, which might be the most significant of the verses for western Christians. This is a prophesy that declares Israel will call another nation to faith ... yet somehow Israel has does not know of this country, and likewise that country does not know Israel.
One thousand years, and two total destructions of two Jewish countries and the rise of the greatest empire in history later, the first Christians - who are Jewish - will call the entire Roman Empire to faith in the name of Jesus. At that time, there is no such nation as Israel, for the Jews are recognized as a religious sect in the region of Judeah. At no time when Israel/Judah existed did the Roman Republic/Empire exist. Two nations that never, ever knew each other ... and Israel calls Rome to faith.
Application: While we read the prophesy about the calling of the Gentile world to faith, Paul explains the same concept in Ephesians 2 (today's New Testament reading). He actively declares that, by faith in Jesus, Jews and Gentiles are now one people united by that faith, reconciled together, and thus not in conflict. In other words, the prophesy of Isaiah 55:5 is complete, for the Jews have called the Gentiles, and they (especially the faithful in Ephesus receiving this letter, but certainly everyone who believes in Jesus in the last 2,000 years) have come running.
Prayer: Lord, as we continue to see terrible issues about both war in and around Israel and violence toward Jews everywhere in the world, may we please take more seriously your call and you plan, to be one people, united by faith in Jesus, and this is not just a unity of faith but a reconciliation of Gentile faithful and all Jews. May we, the Church, better find our voice and leadership in this matter, individually and collectively. Amen.
