According to the book, the prophet, exiled in Babylon, experienced a series of seven visions during the 22 years from 593 to 571 BC, a period which spans the final destruction of Jerusalem in 586. The visions, and the book, are structured around three themes: (1) judgment on Israel (chapters 1-24); (2) judgment on the nations (chapters 25-32); and future blessings for Israel (chapters 33-48)
Calvin was a tireless polemic and apologetic writer who generated much controversy. He also exchanged cordial and supportive letters with many reformers, including Philipp Melanchthon and Heinrich Bullinger. In addition to the Institutes, he wrote commentaries on most books of the Bible, as well as theological treatises and confessional documents. He regularly preached sermons throughout the week in Geneva. Calvin was influenced by the Augustinian tradition, which led him to expound the doctrine of predestination and the absolute sovereignty of God in salvation of the human soul from death and eternal damnation.
