There are many different Bible reading schedules that have been created. Some go straight through the Bible. Others follow a chronological order. Some have readings in different genres each day. Some read portions of the Bible (like the New Testament) several times in a year. Others take two years to read through the entire Bible. Justin Taylor has a great overview of many plans, which you can read here.
I encourage you to find a plan that will work for you. If you get too behind, simply pick it up on the assigned reading for today and press on. Don’t be discouraged. I plan on reading using M’Cheyne’s schedule (which Justin Taylor explains). I hope to read through the entire Bible this year with my son.
