This book represents a slightly modified version of my Ph.D. thesis, written at the University of Aberdeen and the University of Tübingen, under the supervision of Dr. Simon J. Gathercole (Cambridge). At the beginning of my post-graduate programme, I had the opportunity to attend a colloquium on the topic of divine and human agency in Paul and his cultural environment. During one of the sessions, Professor John Barclay made a comment stressing that much more work still needed to be done in comparing the Book of Wisdom and Romans.
