Because He's Worthy in a practical workbook that blends the ""spirit"" side of worship with the ""understanding"" side to help local churches improve their worship experience. I wrote this book because there are no books that sufficiently cover both the practical application of music theory and the scriptural foundations of worship in church music. It is unique in that it is a a book that can be studied both individually or in a group (with the study/application sections) and, because of its practical nature, it will produce noticeable results in the quality of music in a local church.
