“Several strong forces oppose our relentless and systematic interrogating of Biblical texts. One is that it consumes a great deal of time and energy on one small portion of Scripture. We have been schooled (quite erroneously) that there is a direct correlation between reading a lot and gaining insight.
But, in fact, there is no positive correlation at all between the quantity of pages read and the quality of insight gained. Just the reverse for most of us. Insight diminishes as we try to read more and more.
Insight or understanding is the product of intensive, headache producing meditation on two or three propositions and how they fit together. This kind of reflection and rumination is provoked by asking questions of the text. And you cannot do it if you hurry.
Therefore, we must resist the deceptive urge to carve notches in our bibliographic gun. Take two hours to ask ten questions of Galatians 2:20, and you will gain one hundred times the insight you would have attained by quickly reading thirty pages of the New Testament or any other book.
Slow down. Query. Ponder. Chew.”
