One can never have enough books, even in the case of second and subsequent editions! This is the case with Craig Blomberg's Jesus and the Gospels: An Introduction and Survey, Second Edition (B&H). The first edition, which I have owned for about 10 years, is a truly outstanding resource. The only other Jesus and Gospels survey that matches it is Mark Strauss' wonderful Four Portraits, One Jesus: An Introduction to Jesus and the Gospels. The second edition, is slated for a July release, and will be well worth the money and wait.
A second notable release is one by my a mentor and friend, David deSilva. Seeing Things John's Way: The Rhetoric of the Book of Revelation (WJKP) is slated for a late June release. David is a brilliant scholar and I know of no finer interpreter of the Apocalypse and the language it employs than he. Two books, 800 plus pages, and anywhere from $70-100 will put these two neatly on your shelf. As Augustine said, "Take up and read," or my version "Save up, and read!"
