Maybe the typical JW is referring to their daily scripture from the past yearbooks that the WT provided. So I guess one scripture a day is reading the bible for them.
Very easy to excerpt the notion that the 'light is getting brighter' re Proverbs 4:18 as pertaining to a change in a WTBTS doctrine. If you take it further and read the entire chapter of Proverbs 4 then you understand the following:
Proverbs 4:18 was not intended to be prophetic indication that God gradually reveals truth to the Watchtower Society. When taken in entirety the context of Proverbs chapter 4 is a comparison of behavior between good and bad people, not the dispensing of doctrinal truth through an organization. From the outset, it can be seen that using this Scripture to discuss doctrinal errors and changes is without basis.

There is reading a scripture from the Bible and then there is reading the Bible.
