John Calvin’s dedication to preaching verse by verse through the Bible was impressive. He was a firm believer in preaching from the original language, in the historical-grammatical approach, with application to the hearer. What is even more amazing is to see the shear number of sermons he preached on various books of the Bible (emphasis mine):
Calvin’s method of preaching is well-documented: it was consecutive, expositional preaching through various books of the Bible. He would begin in verse 1, chapter 1 of a particular book and then preach through the book until the end. The next sermon would begin a new book, and he would preach that book sequentially until finished. This is serial preaching at its best. Calvin’s immediate movement to preach one book after another is what Gerstner calls ‘chain preaching.’ He spent, for example, one year preaching through Job, a year and a half on Deuteronomy (200 sermons), and three years on Isaiah (350 sermons).
According to Beeke, ‘The average length of texts covered in each of Calvin’s sermons was four or five verses in the Old Testament and two or three verses in the New Testament. His sermons were fairly short for his day (perhaps due in part to his asthmatic condition), probably averaging thirty-five to forty minutes.’
