Green is a recognized Gospels expert, so his recommendations are very worthwhile. I echo his choices, esp the works of RT France, and please do check out Marianne Meye Thompson’s new John commentary – it is spectacular! Here are some of my favorites in addition (not that you asked):
Matthew: Hagner (WBC) – phenomenal exegetical work, but also his pastoral and theological insights are profound.
Mark: Morna Hooker’s short work on Mark is one of my favorite (BNTC), and I would also add Larry Hurtado’s brief, but valuable NIBC volume.
Luke: I would add Mikeal Parsons’ Paideia volume, and note that RT France wrote the Teach the Text commentary on Luke (Baker) just before he passed away – it is a goldmine for pastors!
John: Lincoln is my favorite, but it also is worthwhile to mention Moody Smith’s Abingdon volume – lots of insight packed into a short volume.
Acts: Truth be told, I often return to classics like FF Bruce (NICNT) and Richard Longenecker (Expositor’s). But Gaventa is certainly the best for brief exposition and literary-theological insight.
