Over the next several days, I diligently used the book. I decided some of the choices I made with my initial set-up weren't very helpful. I tweaked it a bit. I kept up with the reading for a while and was really starting to get into a groove with the book. I really like it.
Then, for various reasons (none of them good), I got out of the habit of using the book. Not surprisingly, my prayer life suffered. Where I had been establishing a regular practice of prayer, I found myself sliding back into a more haphazard pattern of personal prayer. Several times, I almost started using the book again, but quit just short of actually opening it.
I recently picked it back up and resumed using it. Hopefully, I won't set it back down again.
Treasury Of Daily Prayer is a Lutheran resource, and that fact is especially evident with the selection of readings that are appointed for each day. They're all form the early reformers and many of them are from Luther. So if you know that's going to cause you to argue with the book instead of use it to guide your prayer life, stay away from it. Otherwise, I highly recommend this book. It's great for individual use. I'm sure it's great for family use, too -- there is a lot in it that is in call-and-response format. For me, it's especially great because it helps make sure I stay focused when I use it.
I can't add any more in the way of a review that Michael didn't say in his review, so read what he said and imagine me agreeing with pretty much everything he says in it.
