Matt Evans has posted a great interview with Dan Wallace on his blog. I recommend that you read it in its entirety (read it here), but I wanted to quote a section here that I found to be the most interesting. Matt asked him, “What areas do you think New Testament Greek scholars will have to focus on in the next ten years?” Here is the answer that was given:
There are also key areas in NT study that are heating up, issues that need to be honestly examined in the next couple of decades by all sides. Among these are the relation of the Apostolic Fathers to the NT (in terms of quotations from the NT, emerging canon consciousness, ecclesiological developments, the Fathers’ view of grace, and whether the AF and the NT reflect the earliest form of Christianity or just that form that became the dominant one).
Another area is pneumatology: What does the NT really say about the Holy Spirit? As strange as it may sound, work in Second Temple Judaism is key here.
A third area is textual criticism. This has emerged as one of the most hotly debated NT topics in recent years. There are those who say we can’t get back to the autographs—the wording of the original NT documents. But some new technologies, along with a better collection of the data (e.g., through digital photographs, made accessible to scholars through the Internet), are helping to get us through this impasse.
Finally, the historical Jesus, Christology, and soteriology are becoming major areas once again. Some genuine breakthroughs in historical Jesus studies are taking place right now, and with it, a fresh look at what Jesus taught about himself, God, social activism, salvation, etc.
For those who are thinking about narrowing your focus as you work on an MA thesis, or a ThM, or even your PhD consider the list from Wallace: Apostolic Fathers and the NT; Pneumatology; textual criticism; historical Jesus studies; Christology; soteriology.
