Tomorrow, Monday the 21st of January will be day 15 of reading through the Bible in 90 days with this session. The day's reading is Dt.23:12-Dt.34:12. I am caught up. Kathryne, having waited late to start, has decided to read the One Year Chronological Bible instead. I am perfectly fine with that because my goal is for her to be in God's Word- however she may do that.
I know some people have trouble with the concept of reading through the Bible in 90 days because the read through is so quick that it doesn't leave much time for meditation. I think it probably depends on the person and on your own reading style, speed, and purpose.
I skim read much of the time. I read quickly. If I read over something and find myself not quite "getting it" I slow down and read it again. But I've always been a quick reader and have had really good comprehension even reading very quickly. I've never been one to do lots of journaling as I read the Bible- maybe this is not a good thing. So I don't miss that aspect when I read through in 90 days. I do have a notebook with me much of the time, and occasionally I think of questions as I read, and I jot them down to think about/look up/study later. But I've never really written down lots of thoughts while I read.
I find that, as a good reader, I find many excuses to just "skip one day" if I am using a through the year reading plan. The amount of reading isn't very much each day, so it is easy to rationalize skipping a day. This defeats the purpose of staying in God's Word daily.
So really the reason that I have so much loved this method of reading is that I am continually in God's Word. I rarely skip a day because I know the next day's reading will be so much. And I'm finding that the more times I read through, the more of a big picture understanding I think I'm getting. This has answered some questions I've had about spiritual things, and it has raised other questions that I'm constantly pondering. It's a great way to keep growing and learning spiritually.
So if you've ever thought you wouldn't want to read the Bible in 90 days because you couldn't study it deeply... you are probably right. Read through in 90 days to get a big picture overview. Then take time in between readings to do more in depth study of a topic or a book.
