Perhaps the most important piece of writing I have read since I first picked up a Bible and read it with any understanding (with some help of some friends) is this modern translation of the new covenant writings from Walter J. Cummins:
A Journey through the Acts and Epistles
The Authorized King James Version with Notes and a Working Translation of the book of Acts, and the personal epistles of Paul
Translated and edited by Walter J. Cummins, Scripture Consulting
He calls it a "Working Translation", meaning it is always under development, and does not claim to be the final authority or word on the subject of translating the Scriptures into English, nor in understanding the Author's original intention or meaning. How refreshing!
Numerous other people have assisted Mr. Cummins in the work; and the work represents a lifetime of disciplined and respectful biblical research by one of the world's foremost scholars of biblical texts and biblical understanding.
You can order your own copy of Journey from Daniel Bader's web site. It is a very nicely bound hardback. You can read a digital version over at Peter Coad's web site, which is a kind of interlinear, and which you may have to sign up for to take advantage of.
