See, I made [David] a witness to the peoples, a leader and commander for the peoples. See, you shall call nations that you do not know, and nations that do not know you shall run to you, because of the Lord your God, the Holy One of Israel, for he has glorified you. (Isaiah 55:4-5)
First, God calls out:
Come, everyone who thirsts,
come to the waters;
and he who has no money,
come, buy and eat!
Come, buy wine and milk
without money and without price.
Then, God makes the astounding promise:
I will make with you an everlasting covenant,
my steadfast, sure love for David.
What did God do for David? Our verses today tell:
See, I made [David] a witness to the peoples, a leader and commander for the peoples.
And then the promise to those who come, by analogy:
See, you shall call nations that you do not know, and nations that do not know you shall run to you, because of the Lord your God, the Holy One of Israel, for he has glorified you.
This is the promise that God made to Israel. And God has fulfilled this promise, although in the strangest way. Israel was, and is, a witness to the one true God, and people from many nations became God-fearers through them. But, marvelous to say, God came to Israel in the flesh, the Word made flesh and dwelling among them. The gospel of Jesus went out throughout the world as his early followers, all born Jews, crossed the Jew-Gentile borders and a new “spiritual” Israel came into being. Thus, “all nations ran” to Israel because of the Lord, and gloried Israel by extending its borders beyond the land of Israel throughout the world.
It’s a very real crime that the new “spiritual” Israel returned the favor with centuries of pograms and persecutions against Jews in their midst, rather than recognizing them for the people of God the scriptures call them (in both testaments).
Still, we must continue to bear witness the best we can, we who have no money, to the goodness of God, and remember that God’s promises to David and to Israel (to Jews and Gentile believers alike) is an everlasting one.
