I thought the book had some very good points.
I am not sure you could call it ‘scholarly’ but ‘logical’ might be a better description.
It asks you to take ‘leaps of faith’. For example, the argument is made that the United States is a lot like Israel in the OT. Both were founded on the religious concepts. Both did well until they turned from God. Both suffered as a result.
Is that scholarly? I’d say probably not.
But it is logical.
A primary characteristic of a scholar is someone possessing or showing a great deal of knowledge, especially knowledge of the subject in question. I'd suggest that Jonathan Cahn meets these requirements.
Both were founded on the religious concepts.
More, both Israel and America entered into covenants with God.
