Things can lose their meaning and become rote when the experience is the same, over and over. If you've been reading Psalms regularly, you may have noticed your mind start to wander as you move from one familiar topic to the next. The Shuffle Psalter provides a daily reading that won't be the same every time.
The Psalms are shuffled, with an additional goal of keeping the daily readings approximately the same length. In 59 days (though this can vary slightly as the process is random), with daily visits to the Shuffle Psalter, you will read all 150 Psalms. After completing an iteration, the Psalms are reshuffled and a new trip through them begins.
The site is updated once per day with a new reading.
