Reading a book of the Bible thru several times has the benefit of focusing one of the larger context, especially if one does this at normal reading speed rather than the slower devotion speed. A slightly dynamic version may help for some of the read-thrus.
The larger context helps one understand the structure of shorter passages. Let us say that a small passage may have a several different but legitimate interpretations. Based on the grammar, some may be more probable, others possible, perhaps some unlikely or even impossible. But in the larger context some interpretations become more likely than others. Interpretations of roughly equal likelihood when viewed at the level of sentence can dramatically change in their relative probabilities when viewed at the level of paragraph, section, and book.
