Some of the most helpful blogs (in my opinion) are those which frequently offer little exegetical insights into passages of the Greek New Testament. A few that I frequent:
- Decker’s NT Resources Blog
- Campbell’s Read Better Preach Better Blog
- Runge’s NT Discourse Blog
- Goodacre’s NT Blog
- Bird will sometimes offer up some nuggets at Euangelion
- Wallace (when he writes) at Parchment & Pen
These folks are not only scholars; they are true teachers.
