I've always loved the epistle to the Philippian Christians. Because of this, I've got a pretty good understanding of the text in English. I even had the great blessing of taking an intensive summer course in seminary from Dave Black on this book. It is one of his favorites; even though the course focused on the English text, Dave still couldn't resist delving into the Greek, which was great for all of us.
Now the goal is to gradually work through the Greek text of Philippians. My plan is to translate it verse-by-verse about five times. By that point I hope to have a good feel for the verbs and participles. More importantly, my desire is to better comprehend Paul's primary themes in the letter.
I encourage all of you to venture into NT Greek in any way you can. If you don't have access to Greek classes but do well learning from books, then this is a good way to start.
