For 2013, I customized two chronological Bible reading plans — one for the Old Testament (plus two of the gospels) and one for the New Testament (plus the Psalms). You can download those plans here in PDF format.
For those who use the Bible program Accordance — my favorite for the Mac, and one I use daily — I have created tools for you to download and use in Accordance. Last year’s NT Bible reading tool is still available on the Accordance site (or you can download it directly here). I am hopeful that the Old Testament plan and the updated New Testament plan will be posted to the Tools page within a couple of weeks.
