You know this how?
You know, it's the WORD that brings faith, not how it's internalized.
The method of delivery is unimportant because that's not what leads to faith.
The WORD is living and active and sharper than any double edged sword. It's inherent in its nature.
I certainly believe in the value of Holy Scripture, but I don't believe it's magic, or that magical thinking is intended by the scripture referenced.
How big a dose you figure works every time? :)
