From Don Carson:
Fight with every fiber of your being the common disjunction between “objective study” of Scripture and “devotional reading” of Scripture, between “critical reading” of the Bible and “devotional reading” of the Bible. The place where this tension usually first becomes a problem is at seminary. Students enter with the habit of reading the Bible “devotionally” (as they see it). They enjoy reading the Bible, they feel warm and reverent as they do so, they encounter God through its pages, some have memorized many verses and some chapters, and so forth.
Seminary soon teaches them the rudiments of Greek and Hebrew, principles of exegesis, hermeneutical reflection, something about textual variants, distinctions grounded in different literary genres, and more. In consequence, students learn to read the Bible “critically” or “objectively” for their assignments, but still want to read the Bible “devotionally” in their quiet times. Every year a handful of students end up at the door of assorted lecturers and professors asking how to handle this tension. They find themselves trying to have their devotions, only to be harassed by intruding thoughts about textual variants. How should one keep such polarized forms of reading the Bible apart? This polarization, this disjunction, kept unchecked, may then characterize or even harass the biblical scholar for the rest of his or her life. That scholar may try to write a commentary on, say, Galatians, where at least part of the aim is to master the text, while preserving time for daily devotional readying.
My response, forcefully put, is to resist this disjunction, to eschew it, to do everything in your power to destroy it. Scripture remains Scripture, it is still the Word of God before which (as Isaiah reminds us) we are to tremble, the very words we are to revere, treasure, digest, meditate on, and hide in our hearts (minds?), whether we are reading the Bible at 5:30 AM at the start of a day, or preparing an assignment for an exegesis class at 10:00 PM. If we try to keep apart these alleged two ways of reading, then we will be irritated and troubled when our “devotions” are interrupted by a sudden stray reflection about a textual variant or the precise force of a Greek genitive; alternatively, we may be taken off guard when we are supposed to be preparing a paper or a sermon and suddenly find ourselves distracted by a glimpse of God’s greatness that is supposed to be reserved for our “devotions.” So when you read “devotionally,” keep your mind engaged; when you read “critically” (i.e., with more diligent and focused study, deploying a panoply of “tools”), never, ever, forget whose Word this is. The aim is never to become a master of the Word, but to be mastered by it.
