I read the entire New Testament once as a sort of a canon. Not much if anything really stuck to my mind, though I am sure something did get stocked somewhere in the depths of my soul. I have heard similar stories from others. It doesn't work if you try to force into you. Nowadays, I read the Bible rather sporadically, but pick stuff up from services, from articles, from sites, from talks, etc., and while I am very far from an expert in the Bible, what I do know is very meaningful and useful. That's what I would recommend -- that what you read is meaningful and gets filtered through your entire being (mind, heart, action). Anyway, it depends on each person and each situation. Some people can probably read it and memorize a lot of stuff. It didn't happen for me because I am not that sort of learner and I was under pressure to read it all. It's actually the times when I was not trying to read but was deeply interested in the subject when I learned the most.
