New Testament Greek has become more accessible than ever in the last several years, thanks to great digital and online resources, but also to some very good New Testament/Greek scholars. B&H Academic is about to release an intermediate textbook that, I think, might just become a new standard. Kostenberger, Merkle, and Plummer set out to make an intermediate Greek grammar that was more than a reference volume, and generally succeeded. While the main part of each chapter does actually seem like a normal reference work to me, this resource also includes some special features. The most significant inclusion for me was the Greek reader at the conclusion of each chapter. I appeal to the wisdom of many Greek teachers that one of the most effective ways to learn Koine Greek is to simply read the New Testament in the original language. However, on most points within the text that teaches the grammar, the authors cite plenty of biblical examples. All three professors teach at Baptist seminaries, so you may encounter some Baptistic interpretations, but I didn’t notice anything major in the portions I was able to read (of course, I am a Baptist as well…). Overall, this book was tailored to be a college/seminary textbook, which is why they’ve written a standard semester worth of 15 chapters (1 per week), but there are a lot of other online resources provided as well like quizzes and Power Points. It is roughly 500 pages too, so it will take some time to work through, but would be time well spent.
