A long-dead guy named Robert Murray M'Cheyne, that's who. I've never read him, and I've barely heard of him, but apparently he wrote a popular "Daily Bread," a "calendar for reading through the Word of God in a year." The following comes from Jeremy Smith, executive minister at First Presbyterian Church in Jackson, Mississippi, and managing editor of reformation21:
M’Cheyne's reading plan averages about four chapters a day, but it rewards the follower with reading through the Old Testament once and the New Testament and the Psalms twice in one calendar year. M’Cheyne envisioned two chapters to be read as part of a daily family time of devotion and two chapters were designated for private reading.
This year we have enlisted the help of several friends of reformation21 throughout the English-speaking world to provide brief, daily, devotional reflections and comments that mirror M’Cheyne’s reading schedule.Not being given to such reading schedules as M'Cheyne's original (for the life of me, I have a hard time reading anything so rigorously planned out), I nonetheless think riffing off of his schedule, as Ref21 has done beginning this past January, sounds like a good idea.
The authors have taken different approaches in their comments. Some have focused on one or two verses at a time from one of M’Cheyne’s suggested daily readings; others have traced the week chapter by chapter through a particular book of the Bible; still others have weaved a narrative of some theme that has appeared in all of the daily readings.
