No, not English and British Lions rugby legend Jason Robinson, but Australian theologian Donald Robinson, one of the theologians who has influenced me most over the last few years. He is one of a rare breed: a conservative evangelical theologian who does NOT subscribe to (what I consider to be) the unhelpful and unbiblical (but sadly prevailing) view that the church is the "New Israel". He has recently been honoured with a compilation of essays to accompany the publication of his Collected Works. My Aussie mate Rory Shiner, who put me on to Robinson a few years ago, gives details of the collection here.
Alternatively, you can download Robinson's BRILLIANT chapter on "Jew and Gentile in the New Testament" (in his book Faith's Framework) for free here.
