It is crucial for the Greek student to move beyond a surface level understanding of the language. Language communicates much of what it communicates at a level much broader than the word, phrase or even clause level. It also communicates much more than just the grammar and syntax of the word, phrase, or clause.
When studying and analyzing Greek, we must learn to broaden our perspective. For example, a genitive absolute may function on the larger discourse level to introduce a new pericope. The “Historic Present” may do the same. Communicating more than vividness, the HP may introduce a new pericope that calls attention to a previously introduced character in the narrative.
Conjunctions may function on the discourse level to introduce a subsection of a pericope. They may also highlight an action, event, or character in the narrative. Verb tense often functions on a larger discourse level to highlight certain actions, events, or states, communicating much more than merely perfective or imperfective aspect.
If this way of approaching biblical Greek is new or unfamiliar to you, I encourage you to investigate this issue further. Here are a couple of good places to start:
“A Discourse Analysis of Matthew’s Nativity Narrative,” by William Varner, in Tyndale Bulletin 58.2 (2007) 209-228. Here is a link that will take you to this issue of the Tyndale Bulletin – http://www.tyndale.cam.ac.uk/index.php?page=frame&add=http://www.tyndalehouse.com/tynbul/tb58-2.htm
The Book of James–A New Perspective: A Linguistic Commentary Applying Discourse Analysis, by William Varner, Kress Biblical Resources, 2011. Here is a link to Amazon where you can purchase the book: http://www.amazon.com/Book-James—New-Perspective-Linguistic/dp/1934952125/ref=sr_1_1?s=books&ie=UTF8&qid=1309801624&sr=1-1
There are many other excellent resourses available to help you move beyond the surface level of Greek grammar and syntax, but these will help get you started. The first is freely available online. The other is worth purchasing because it deals with an entire book of the New Testament — one that is notoriously difficult to analyze and structure.
