Planning and leading times of community worship that are spiritually forming is challenging. We've been lead to believe that "music equals worship", "old is bad, but new is good", "worship is a personal matter", "worship is a Sunday thing", "the worship leader is the one who leads the singing", etc. Thankfully, every year Sovereign Grace Ministries hosts the WorshipGod Conference, which is designed especially for pastors and musicians. You'll find articles like "Beholding the Glory of God's Supremacy" to deepen your biblical theology of worship as well very specific, practical articlkes like "Making the Most of Rehearsals."
