I have a hunger to straighten out theological, exegetical and Gk questions. But all this about upgrading, isn't it to a large part about social pressure?
I see others buying, studying, and knowing so much. I don't get envious about what books they own - I rarely look at what exact items others have. But this social pressure causes a stress to make up my mind quickly during the sale so that I get books that I desire.
But thinking about it from a different angle: if I would devote less hours to Christianity I wouldn't need to buy as many books
