I am not sure how many of the OBC blog readers can read Greek (please spare me the "It's all Greek to me!" You have no idea how many times I heard that in college/seminary). :-)
But this website makes Greek a little more accessible for people who want to study their Bible in fresh ways. It is amazing what is available online (for free)!
PS: I can't help but mentioning 3 other sites that I enjoy (9Marks, Na:Humble Orthodoxy, and DesiringGod).
