A nice thought, pilfered off my Bible Interpretation online thing.

Read the introduction to chapter 6. Notice that the authors are not saying that God can not (or even does not) use the procedure of grabbing random verses, they are just saying that such use of the Bible is not a fair or proper reading of the Bible as it demands a miracle (even if a small one) from God. I think of it as being like walking up to a door and waving my stick at it expecting it to open for me like the sea did form Moses, instead of turning the handle and pushing. Studying the Bible using the usual methods for studying texts is like opening the door the usual way ;)
