Below is an excerpt from the Introduction to “The Controversy of Zion and the Time of Jacob’s Trouble” in which I give an overview of the core message of the book.
The aim of this book is to encourage Bible saturated thinking, biblically inspired feeling, and biblically responsive living at the end of the Age in relationship to this issue of Israel.
Between the prominence of Israel in biblical prophecy, the contemporary Israeli-Palestinian conflict, mounting anti-Semitism in the nations, increasing anti-Judaism in the Church, and the ever-evolving socio-political landscape in the Middle East, I believe there are more than enough reasons to legitimize an honest study of what Scripture has to say about “Jacob” and their “final”  “affliction.”
THE UNPRECEDENTED INTENSITY OF JACOB’S TROUBLE
The impact of “the time of Jacob’s trouble” on the Jewish people will be far more horrific than any of us can imagine. When it was shown to the Hebrew prophets they were burdened in anguish. Jeremiah was disturbed and appalled. Habakkuk trembled and quivered. Ezekiel mourned and grieved. Daniel was sick for days.
According to Scripture “the time of Jacob’s trouble” will eclipse every other historical epoch of Jewish suffering in intensity—even the Holocaust of Nazi Germany.
In his book, Hitler and the Holocaust, Robert S. Wistrich writes:
“Thinking about the Holocaust is like staring into an abyss and hoping it will not stare back. It is the ultimate extreme case, a black hole of history that not only challenges our facile assumptions about modernity and progress but questions our very sense of what it means to be human.”
Historically speaking, Wistrich is correct: the Holocaust of Nazi Germany is the “ultimate extreme case.” But as far as the future is concerned, it is but a precursor of what is to come.
If the systematic annihilation of over six million Jews is “like staring into an abyss and hoping it will not stare back,” to what shall we liken the consideration of the future crisis? The prophet Zechariah was shown that “two-thirds” of the global Jewish populationalive in the generation of “Jacob’s trouble” will not survive.
THE FUTURE INVASION OF THE STATE AND THE FLIGHT OF THE JEWISH PEOPLE
As these brutal events unfold in the future, they will have severe implications for the recently established Nation-State. When the military invasions begin, the State—as we know it today—will be dominated by foreign armies and much of the population within will either escape voluntarily or be “driven out” against its will.
Zechariah 14:1-3 makes clear that though a remnant of besieged Jews will remain in the city of Jerusalem throughout the conflict, only half the city will remain intact (if we can even call it that) as the Nation is overun by invading forces. Isaiah was told that if the Nation were likened to a tree, only a “stump” would “remain” in the wake of the trouble. Then, without the use of metaphor, the Lord told him that only “a tenth will remain.”
With that said, we Gentiles need to understand that “Jacob’s trouble” isn’t just Jacob’s problem.
The escape and expulsion of the Jews from their crippled and war-torn State will dramatically impact the Church among the nations. In the coming days when the violence begins, potentially millions of Jews will take to “flight” “among the nations,” seeking refuge from their “tormentors.” They will need to be received and served by those who have anticipated their arrival. Much like Corrie ten Boom and her family who secretly housed and protected Jews during the Nazi Holocaust, so also will the Church in the “great tribulation” be called upon to serve disoriented, panic-stricken, and traumatized Jews who will then be the object of international scorn—even from nations in which they have, up to now, enjoyed a measure of safety.
It will be required of us to sacrificially identify with the “least of [Jesus’] brethren” who in that day will be “hungry, thirsty, estranged, naked, sick, and imprisoned” in the extremity of their final “trouble.” This is the inner-most meaning of the parable of the sheep and the goats in Matthew 25:31-46 and the reason Jesus chose to end the Olivet Discourse in Matthew 24-25 this way. The issue of how we treat the Jews in our midst as they are “sifted among the nations” in the “great tribulation” really matters to the Lord.
PREPARING FOR WHAT IS TO COME
The hour in which we live is urgent. With substantial Jewish presence on Jewish soil in a politically independent Jewish Nation-State for the first time since the generation of the apostles, and with the religious and political landscape of the Middle East rapidly evolving, we must discern the times.
Much like the generation of Europeans on the back side of World War I that watched the rise of Hitler and the formation of the Third Reich, I believe we’re living in a transitional moment of human history. But the difference between the crisis of the Second World War and the future “time of Jacob’s trouble” will be three-fold:
First, the crisis to come will have its inception in the Land of Israel, not in a foreign nation.
Third, the crisis will culminate in the salvation of “all Israel” when the Jewish people will be “delivered,” “saved,” “gathered,” “redeemed,” “healed,” “awakened,” “cleansed,” and “brought into the bond of the Covenant” after “looking upon Him whom they have pierced” with deep sorrow and love.
 The name of the patriarch from which the Jewish people trace their lineage. Israel as a national identity is often referred to as “Jacob” in Scripture. See Jeremiah 30:7.
 Ezekiel 35:5-6
 See Jeremiah 30-31; Zechariah 12-14.
 Jeremiah 30:5-7
 Habakkuk 3:16
 Daniel 7:28; 8:27
 Matthew 24:21-22, Jeremiah 30:7, and Daniel 12:1-2 all declare that nothing before or after this trouble will exceed it in intensity.

 Zechariah 13:8-9
 Zechariah 13:8-9; a passage we will return to in subsequent chapters.
 The State of Israel was established in 1948.
 Matthew 24:15-17; Daniel 9:27; 11:31-44; Joel 3:2-16; Zechariah 12:1-2; 14:1-3; Ezekiel 38:1-12; etc.
 Jesus commanded the population in Jerusalem to escape when the final invasions begin. See Matthew 24:15-22.
 Isaiah 11:11-16 and 27:12-13 speak of the “banished ones” who will be “driven out” of the Land of Israel into nations like Egypt, Iran, and Iraq.
 See also Daniel 11:31-36; Revelation 11:1-2; Luke 21:20-24; Matthew 24:15-22.
 See Isaiah 6:10-13.
 Reggie Kelly often uses this phrase to counter the Gentile assumption that we will be exempt from this hour of Jewish suffering.
 Sometimes we read of voluntary Jewish escape (as in Matthew 24:15-7), and other times we read of involuntary expulsion whereby the Jews are “driven out” and “banished” from the land (as in Isaiah 11:11-16 and 27:12-13).
 Matthew 24:15-17
 This expulsion was called, “sifting through all nations,” in Amos 9:9-10.
 Isaiah 51:23
 Amos 9:9-10
 Though this may seem like a novel reading of the parable, the context is decisive. The time of tribulation in Matthew 24:21-22 will result in the expulsion of the Jews from the Land in Matthew 24:15-20. How we respond to them when this unfolds is important.
 As of 1948 and 1967; see chapter 7.
 Matthew 16:1-4; Amos 3:7
 Matthew 24:14-22; Zechariah 12:1-2; 13:8-9; 14:1-3; Joel 3:2-21
 The Book of Revelation portrays the Church of Jesus as “prepared” (19:7), praying (22:17), prophetic (10:1-11), and persevering (14) during the greatest crisis in human history.
 The majority of the church of Germany was seduced by doctrines of demons and abandoned the Pauline mantra that “the gospel…is the power of God for salvation to everyone who believes, to the Jew first…” (Romans 1:16). People like Dietrich Bonhoeffer and Corrie ten Boom were the rare exceptions in the apostasy of the German church in the time of the Holocaust.
