If you know that you are ready to commit yourself to a 6-year Bible study plan, you want to make sure that you can truly devote such a length of time that the Bible requires to fully study and understand. During a 6 year plan, you want to make sure that you can devote at bare minimum at least eight or nine of the twelve months to your Bible study course. You can leave the remainder of the year for other studies, such as doctrinal and practical studies. Once you get started with your Bible book study plan, you will be able to better determine how you will spend your time, as experience will help your balance your schedule as well as determine how thoroughly you will be able to study.
