Louis Berkhof (1873 – 1957) “was a Reformed systematic theologian whose written works have been influential in seminaries and Bible colleges in the United States and Canada and with individual Christians in general throughout the 20th century” (CCEL). Berkhof taught at Calvin Theological Seminary in Grand Rapids, Michigan from 1906 – 1944, and served as its president during his last 14 years there. Wayne Grudem called his Systematic Theology, published in 1932, “a great treasure-house of information and analysis…probably the most useful one-volume systematic theology available from any theological perspective.”
Nine years before his death, in 1948, Berkhof watched modern Israel become a nation. Three years later, in 1951, he published a book with a long title: “The Kingdom of God: The Development of the Idea of the Kingdom, Especially Since the Eighteenth Century.” Here’s a quote from that book, concerning ancient Israel and the emergence of a modern nation with the same name. What do you think of Berkhof’s statement here? I find myself agreeing with him:
“The theocratic nation itself was merely a type, a shadow of the spiritual realities of a better day, and therefore destined to vanish as soon as the antitype made its appearance. The restoration of the ancient theocracy in the future would simply mean the recurrence of the type – to what purpose? – and not at all the establishment of the Kingdom. It should be borne in mind that the beginnings of the Kingdom of God existed long before the theocracy was established, and continued to develop, and even after it lost its national existence. And the founding of the Kingdom in the new dispensation was in no way dependent on the fortunes of the Jewish nation” (Louis Berkhof, The Kingdom of God…, pp.170-171).
Of course, Berkhof didn’t say that the Jewish people were “destined to vanish,” only national Israel along with its previous significance. As we know, God created “in Himself one new man” from Jews and Gentiles who trust in Him (Ephesians 2:15), and God has kept a remnant from among the Jews (Romans 9:27, 11:5).
At least two earlier posts here also address this topic:
 “Why I Stand With Israel” shows how Isaiah, Matthew, Luke, and John all demonstrate that what was said of ancient Israel in the Old Testament is now said of Jesus. In other words, Jesus is Israel, and it’s no surprise that Paul calls Jesus’ followers “the Israel of God” (Galatians 6:16).
 “Galatians 4 Shows That Isaiah 66 Is Not About Modern Israel” deals with a passage (Isaiah 66) that many say predicted Israel becoming a nation “in one day” in 1948. It shows that Isaiah instead predicted the birth of the Church, the downfall of earthly Jerusalem, and God’s embracing of the Jerusalem from above.
