Here is a re-post of what I have recommended the past few years:
Bible Reading Plans for the New Year!
Allen and I read through one together last year and it blessed our socks off! Doing it together was fun, and always gave us something to talk about as well. Once I heard a few other people were doing it, it was great because we could discuss what we were learning through the scriptures, too.
Justin Taylor had this blog post last year with many different Bible reading plans to choose from. Last year we read the ESV Bible Reading Plan and this year we are going to try the Discipleship Journal Plan (with catch-up days), which will work nicely if you fall behind or if you want to research something more fully on the "off" days. Reading through chronologically could also be very interesting!
So, don't delay! Go choose yours! I highly recommend it.
