While I was on retreat, I began using a new devotional guide for some of my prayer time. The book is Openings: A Daybook of Saints, Psalms, and Prayer by Larry James Peacock. It is published by Upper Room books and came out in 2003.
It is a wonderful combination of daily reflections about great Christians throughout time, psalm reading, and suggestions for various prayer practices. It teaches breath prayer, lectio devina, prayer of presence, and much more. It is a calendared book; the author often uses particular dates significant in the life of a saint to write about them on a particular day. But I think it would be fine to just start at the beginning, regardless of what the actual date on our calendar may be. Better to read it front to back rather than start on the correct date because it builds on itself over time.
It never ceases to amaze me how a good prayer guide can make a difference in my day.
You can find it here at the Cokesbury website (our UM Publishing house) for about fifteen bucks. Or you may find it elsewhere.
