I am thankful that when I first begin to read and study in the area of biblical theology that I discovered the work of William J. Dumbrell.  He is very helpful, and I pray he continues to write and publish for many years.  Attached is a summary of his article on the covenant with Noah, an article published in 1979.  I summarized the article for my own purposes when I was first working through many issues in biblical theology.  He wrote a number of articles during that time period which are worth tracking down.  Many of his thoughts on the "big picture" of biblical theology can be found (in a tad more clear and accessible form, imho), in his The Search for Order: Biblical Eschatology in Focus.
