Since I teach beginning Greek frequently, using BibleWorks 8 to help students learn is important to me. One simple feature that pays a wealth of dividends is the vocabulary module. Memorizing vocabulary is hard, and perhaps a little tedious, but it is absolutely essential if one is going to read the New Testament with any proficiency.

BibleWorks 8
I am a big fan of bible software, and as a PC user I have long enjoyed BibleWorks. (I even moonlight for them as a regional trainer here on campus, teaching training seminars for our students about twice a year.) At the end of 2008 they released version 8. I recently installed it, and really like what I see so far. There has not been any type of facelift to the interface, but there are a lot of modifications both under the hood and on the surface which make it a worthwhile investment
