is by praying the psalms.
Mrs Felix & I began praying the psalms as a bit of an Advent thing, and have found it to be a rewarding thing to do.
Why the psalms? And why the title? Because by praying the psalms, I find (and you might too) that pretty much every facet of one's inner world is exposed by some burst of anger, some shout of praise, some sigh of longing, which is found somewhere in the book of psalms. Allowing the voice of the psalms to shape our prayers has helped us to give voice to those deeper sighs, delights, disappointments, frustrations and joys which are too often covered up in our everyday life. To pray deeply (especially with one's spouse) is, well, a form of spiritual uncovering and nakedness of which one need not be ashamed.
Go ahead. Pray the psalms. Get naked.
