Vic Kovacs and Stephen Mathews are just instruments in this effort. Marilyn Phemister, the reader of the New Testament Greek made two pivotal choices that made this site possible. She picked the Westcott-Hort Greek, which is public domain, and made her readings public domain and freely available before her passing.
We have jointly decided to try helping folks that have few resources learn to read Biblical Greek. There are a great many books out there for introduction to Biblical Greek. Each book offers its greatest benefits and features. During and after plugging away through such a book without a class to attend, as I have, resources start becoming difficult to obtain, especally when funds are tight. Hearing the Greek spoken is a great step in learning it. Having tools to look up the meaning of words is another help but should be used to build an internal vocaulary.
Clicking the chapter name or number, e. g. Chapter 2, will start reading the full chapter text. Work is underway to split chapters into verses. As these become broken out (follow progress here), clicking the verse number will start reading the verse in Greek. The buttons at the top allow you to setup the page to your greatest comfort. For example if you find it easier to study the Greek line by line click the Verse Per Line button. For inline English (the free Webster translation for now) click "Inline English".
