The Puritan conviction about the centrality of the Bible in preaching was reinforced by the practice of largely or exclusively limiting the details of the sermon to biblical material. Puritan preaching was expository in nature, meaning that the entire sermon was to be inextricably tied to the text. The mere establishment of a connection between the sermon and the text was not sufficient for Puritan preachers. Quite the contrary, for, according to the Puritans, "The sermon is not just hinged to Scripture; it quite literally exists inside the Word of God; the text is not in the sermon, but the sermon in the text... Put summarily, listening to a sermon is being in the Bible."
