In the beginning God created the heavens and the earth. Later he kicked Adam and Eve out of the Garden of Eden and decreed that from that date forward, people would have to work very, very hard, just to survive.
From then until recently, if you chose Law as your profession, you did not have to read much further into the Bible to understand what was expected of you.
I once had a partner who I will call Marvin. Marvin was a capable lawyer who had a specialty in a particular area of litigation. Marvin was personable. He could bring in lots of work in his specialty and hold onto clients. Marvin was also smart. He could look at a complex problem, boil it down to its essentials and identify the most practical solution. Marvin was particularly good at developing litigation strategies and he was also very good at negotiating with other counsel and at persuading judges to rule in his favour on all sorts of issues.
