I once read that Timothy Keller reads the same book every single month for the last 20 years. That is the book of Psalms. I always thought this was interesting, why and how do you do that?
A few years ago, I discovered a small system for praying the Bible and more specifically the Psalms that would change my life forever. With this system, I read 5 Psalms per day, after one month, I have already read through the entire book of Psalms.
The book that taught me this was Donald Whitney's Praying the Bible. I highly recommend you grab this book, it's small (less than 100 pages) but so helpful and practical.
Here is how the book teaches us how to read the book of Psalms and at the same time pray the Psalms.
Donald Whitney says that, first, you read the Psalm that corresponds to the day you are reading it. At the time I am writing this post it's June 10th. So I would start by reading Psalm 10. Then, after reading Psalm 10, I would count 30 Psalms, read that Psalm, and then count another 30, read that Psalm, until I have read 5 Pslams. So for today, I would have read the following Psalms; 10, 40, 70, 100, and 130. Third, as you are praying any of these Psalms, pay attention to what God is promoting in you, when there is a Psalm or phrase or word, or verse that gets your attention, pray that Psalm. Whitney gives us an example of how to actually pray the Psalm itself that you can follow. After doing this for a few years, I have discovered my own system for praying through scripture, you can find it here.
And that's it. At first, it may sound a little complicated, especially when having to count by 30 every single day. Below you will see a link to a calendar that I created myself after realizing I needed an easier way to just see which Psalms I needed to read on any given day. I hope this helps.
