I have a great recommendation for a really good book. This is from my friend Virginia and I trust her judgment. Here is what Virginia said about this book.
God Wants to Hear You Sing by Ruthie Jacobsen with Rodney Griffin. Praising God is easy when life is easy. . .What comes from our mouths when life is tough however, is what truly reveals our heart condition. The book is just full of wonderful praise stories. . .how people got through deep valleys, praising the Lord!
