First Fruits of Zion (and Vine of David) is a profound resource for believers in Yeshua. All of their materials are worth checking out (http://ffoz.org/).
Particularly special, however, is their latest issue of Messiah Journal. In addition to a wonderful article on the ethics of Yeshua, there are two biographies of luminaries of Messianic Judaism: Franz Delitzsch and Rabbi Isaac Lichenstein. This articles are informative and timely, as FFOZ and VoD hope to release their special edition of a Delitzch Hebrew/English translation of the New Testament soon.
My personal favorite in this issue is a translation of R Lichenstein's, "The Talmud on Trial," which is an apologetic defese of the Talmud to the Christian world.
There are other excellent articles in this issue, including dicussions of "one law" theology and apologetics for Yeshua's Messiahship.
I cannot say enough good things about the journal or the thankfulness I feel for having the opportunity to take a sneak peek...What are you waiting for...check it out: Messiah Jounal Issue 105 Fall 2010
