Background Buoyancy

In Neutral Buoyancy, journalist and diver Tim Ecott takes you on a guided tour of the history of undersea exploration and the emergence of diving culture. He tells the extraordinary story of man's attempts to breathe underwater, from the sponge divers described by Aristotle, to the development of sixteenth-century diving bells, to the invention of modern scuba equipment. Along the way, Ecott intersperses the story with his own thrilling adventures, from the waters of the South Pacific to the remote islands of the Seychelles, from explorations in the clear, flowing tides of Sardinia to a near-death experience in the cold gray depths of the English Channel. Filled with engaging stories of humanity's conquest of the undersea world -- and heart-pounding action that will leave you breathless -- Neutral Buoyancy is a compelling blend of history and adventure, an exciting overview of the world of undersea diving. "As elemental, entertaining, and stimulating as the environment it traces." -- Kirkus Reviews "Engaging ... Neutral Buoyancy will certainly become cult reading for divers." -- Alexander Urquhart, The Times Literary Supplement "Ecott's encyclopedic recounting of diving history ... should be awarded a place on any diver's reference shelf.

Why was labeling the Pharisees "white-washed tombs" one of the strongest criticisms Jesus could have made? Why were the disciples, after Jesus' death and resurrection, determined to replace Judas and keep their number exactly at twelve? What is the background to Paul's denunciation of homosexual behavior? Why did Paul expect Corinthian women to cover their heads? These and hundreds of other similar questions arise for anyone who reads and tries to live by the Bible. Today's world is very different from the Greek, Roman and Jewish world of Jesus and the New Testament writers. Scholars devote their lives to the study of languages, archaeology and history in order to better understand the Bible and its cultures. But often the results of their studies are found only in academic libraries. For the first time, Craig Keener's Bible Background Commentary: New Testament provides the fruit of scholarly labors in a single volume arranged in convenient verse-by-verse format, covering the entire New Testament. Based on ten years of in-depth study, the Bible Background Commentary will be valuable for pastors in sermon preparation, for Sunday-school and other church teachers as they build lessons, for missionaries concerned not to import their own cultural biases into the Bible, for college and seminary students in classroom assignments, and for everyday Bible readers seeking to deepen and enhance their study of Scripture.
