Christian Zionism — the belief that the modern state of Israel fulfills biblical prophecy — has existed as a theological concept for well over a century. But in the past couple decades its political power and influence in the United States has surged, with many of Donald Trump's closest political allies among its adherents.

Our guest is Daniel Hummel, the author of Covenant Brothers: Evangelicals, Jews, and U.S.-Israeli Relations.
