From the department of straining at gnats and swallowing camels, The Standard Bearer ran a series of posts by David Englesma in 2017 and 2018 criticizing the standard premillennial interpretation of Romans 11, culminating in this one and this one. Based on this chapter (though not exclusively), premillennialists anticipate (in Englesma’s own words), “a mass conversion and salvation of Jews, and their restoration as an earthly kingdom of God in Palestine”.
That’s a fair representation of my beliefs, an exegetical hill I’ll happily die on.
