I came close one year where I read the "through the Bible" plan for about 6 months, then stopped for 12 months, then picked up the next year where I left off and finished it. Not bad.
I think it's a worthy undertaking but the bigger picture is to simply get God's message into your mind regularly. It doesn't need to be a huge plan, start small. Hear are some ideas.
- Read a Proverb. There are 31 so read the one that matches the day of the month, pretty simple.
- Use a Chronological order "read through the Bible " plan but don't worry about the days, just go in order and if it takes you 7 years, no problem.
- Read a single book in the Bible. Maybe a small book like James. Read slow and simply digest, ask God to make it real for you.
