I am a praise and worship leader at my church. I have thoroughly enjoyed Dee Brestin's book, "A Woman of Worship". I highly recommend it to everyone who wants to gain knowledge about praise and worship, enhance their own praise and worship, or help their congregation to come to a better understanding of true praise and worship.
We are using this study for our summer session and the women have been very blessed with the meaningful questions and challenges in this journey through the Psalms. The closing section of each lesson is especially good with prayer being guided by the Psalms being studied. It centers the prayer thoughts on genuine needs. The musical CD is a blessing/bonus.
