The purpose of this book is to provide an accessible, comprehensive biblical philosophy of instrumental music in worship for church instrumental directors and instrumentalists in churches. This information will better inform and enrich their ministry, transforming them as worship leaders, and ultimately, transforming the worship practices of their churches. This book will prove to be a valuable resource for directors, as they justify their ministry in their respective churches, but also as an apologetic to those from churches and denominations who refute the use of instrumental music in New Testament worship. Furthermore, this resource will provide a biblical basis for the practice of instrumental music ministry, beyond a simple justification, examining the scriptural guidelines for the ministry and operation of instrumental music in the worship of the church. This information is formatted in the appendix as a series of devotionals, so directors are able to present it to their instrumental groups, making sure both directors and instrumentalists understand the biblical basis and guidelines for their practice of instrumental music in Christian worship. As the director presents this devotional series to his instrumentalists, he will more effectively internalize the biblical principles of the series, as he is required to study the material and then verbalize it to his group. A biblical understanding of the use of instrumental music in worship is of utmost importance to practicing church instrumentalists and directors. My concern is the fact that a well-defined, comprehensive biblical philosophy on this subject has not been readily available for church instrumental directors. When church instrumental directors are asked to justify their ministry from a biblical perspective, they have had relatively few resources to consult. I have discovered no books dedicated exclusively to the subject, and only two books with a complete chapter devoted to the biblical foundations of instrumental music in worship. On the other hand, there is an abundance of written material readily available concerning the prohibition of instrumental music in worship. Individuals and denominations that generate this material take a position based solely on the regulative principle, otherwise know as the negative hermeneutic. "The 'negative hermeneutic' says that because something is not found in the New Testament - in this case, instrumental music - it is inherently wrong and unbiblical." I be
