My mom and I have started this thing...reading our Bible in 90 days. It's currently day 5, and I'm already in Exodus. It's been a lot of fun, and has really been challenging.
What we did (if you'd care to join us) is looked at the number of pages in our Bible total, then divided them by 90. I have to read 11 pages per day, which is a bit daunting until I consider that I read more than that a day in other books LOL
