Don Whitney has another excellent observation on Bible study. He says,
“If reading the Bible can be compared to cruising the width of the clear, sparkling lake in a motorboat, studying the Bible is like slowly crossing that same lake in a glass-bottomed boat. The motor boat crossing provides an overview of the lake and a swift, passing view of its depths. The glass-bottomed boat of study, however, takes you beneath the surface of the Scripture for an unhurried look of clarity in detail that’s normally missed by those who simply read the text. As author Jerry Bridges puts it, “reading gives us breadth, but study gives us depth.”
