I first began reading N.T. Wright in college. I still had much to learn but I benefited tremendously from his Biblical theology even though over the years I discovered areas I disagreed with him. His understanding of the larger arrangement and an organization of Scripture's larger narrative is quite compelling.
Here is a 40 minute lecture that gives a good overview of Biblical theology. It is worth your time.
