Here is a very fine article at Anglican Compass on
How to read the Psalms for all they're worth, by W. David O. Taylor, a theologian at Fuller Seminary and author of
Open and Unafraid: The Psalms as a Guide to Life. He offers his advice in seven points. An excerpt:
2. Read the Psalms consistently, rather than occasionally and sporadically.
This was Eugene Peterson’s advice to me as a seminary student at Regent College in 1995: to read a psalm a day as a life’s habit. It’s also advice that Christians throughout the centuries have taken to heart. Consider then how you might read a psalm a day yourself. Begin with Psalm 1 and march your way to the end, to Psalm 150, and then start over.
Don’t become too anxious if you miss a day or two, however, or if you get bogged down with the longer psalms. The point isn’t to read the psalms perfectly. There’s no scorecard, thank God. The point is simply to read the psalms over and over again, so that they’ll have a chance to saturate our hearts and minds with the good words of God.
Of course, once you've started to read a psalm a day, you might then move on to take up the
30-day schedule in the Book of Common Prayer's Psalter.
