Most exegetical commentaries on the Gospel of Matthew will provide in-depth analysis on the Sermon on the Mount. Osbourne’s commentary (in the Zondervan Exegetical NT series, which I have been citing in this series of blog posts) provides some helpful insights, as do the commentaries by Nolland (NIGTC), Turner (BECNT), Morris (PNTC), and Blomberg (NAC). Keener’s socio-rhetorical commentary is also helpful (but massive!)
The best non-commentary resource, in my opinion, is Carson’s brief work on the Sermon on the Mount. Carson explains each section in a straightforward manner, and he applies the text to modern believers. As I work though the Sermon on the Mount, I plan on utilizing Carson’s work, so stay tuned for the next few posts!
