I tried reading the NWT from Genesis straight through to Revelation many many times and one time I actually made it. Things got really tough when I got to Isaiah as I found all the prophets utterly arid. I never could get an iota of benefit from any of those books. Matthew to Revelation was somewhat easier. Reading from Acts onwards made me realise that I did not like the Apostle Paul very much at all. He always seemed to come across as a bully to me.
A year and a half ago I got an audio Bible read by Max Maclean and listened to him reading the entire Bible from Gen to Rev which took me 52 days. Even a fair bit of that was hard going at times and I think I did did it more out of a sense of obligation and guilt and as some kind of self-imposed penance and duty rather than a joy or pleasure.
