You have tried before using one of the "in a year" programs only to find after the first few weeks you are already "behind." Soon, a "few days behind" becomes a "few weeks behind." Before long you just give up and decide to wait until next January to start again!
While many of the yearly plans have broken the Bible reading in manageable sizes, there is still the implied idea that it has to be done in a year.
By simply removing the calendar dates, you can remove some of the barriers and hindrances to reading all the way through the Bible.
There are many different plans to choose from. You can read through the Bible from Genesis to Revelation. If you want to start smaller, try just reading through the New Testament. Some plans offer different perspectives by ordering the readings in different ways.
There are plans for everyone.
