My Grandma reads her Bible every night and has read through the Bible numerous times, same is true with my Dad. My Grandma reads straight through from Genesis to Revelation. I jump around too much to keep up with what I've read and what I haven't. The bad thing is that I've even gone to Bible College and still can't claim to have read through the whole Bible.
Anyway, with all that said, I am now trying to read through the Bible in it's entirety. No missing anything, so I can know, beyond a shadow of a doubt, that I have read it all. I am using the one year plan on my iPhone. It mixes things up a little. It allows me to read some of the Old Testament along with a little bit of a Proverb and some New Testament each day. It checks off a box next to the assignment each time I've read something (I really like that). I can keep up with what I'm reading and what I haven't read.
Can't say I've stayed on track daily but it's really easy to get back on track. I just start where I left off and keep going. If I can't do all of a daily reading one day, I just double up the next day.
I'm really looking forward to one day being able to say that I have read ALL of the Bible. It's just one of those goals I've never reached. Hopefully one day, like my Grandma, I can say that I have read through the Bible too many times to count.
