Dallas Willard on Scripture Memorization

I wrote about our family's two primary disciplines, reading the bible one page a day and scripture memorization at a pace of 2 verses a day. We have revised this to 10 verses a week, but anyway. Often people think scripture memorization is too "elementary" or too rote. Isn't bible discussion and bible story telling more effective and, well, cool?
Dallas Willard is a pretty smart and critical thinking kinda guy, and this is what Wilalrd says about scripture memorization in The Great Omission, p 58:

Bible Memorization is absolutely fundamental to spiritual formation. If I had to - and of course I don't have to - choose between all the spiritual disciplines of the spiritual life and take only one, I would choose Bible memorization. I would not be a pastor of a church that did not have a program of Bible memorization in it, because Bible memorization is a fundamental way of filling our minds with what we need, "To have the book of the Law ever before us" (Joshua 1:8)

Simple as it sounds, a few verses a day and rehearsing these verse to and from wherever we are going is fundamental to spiritual transformation.
peace,
