I am currently reading an outstanding book on Reformed Worship. If you want a detailed understanding of why we do what we do in worship, its rootedness in Scripture, the Early Church, and recovered in the Reformation by Calvin, Zwingli, Luther, Beza, and others, then get this book. Here's an important snippet. I do not think it is an overstatement to say that our empty seeker-sensitive worship has not only opened the floodgates to apostasy, but by trying to meet "felt needs" rather than point to God in Christ and growth through His Word, has opened the door to things like the "felt needs" of drag Queens being met by dancing like whores in front of children. If we believe in repentance, then we need to believe in telling our "felt needs" to shut up, because they are often/usually sinful desires. But I digress. Here's the quote below and a link to the book: https://www.heritagebooks.org/products/worshipping-with-calvin-recovering-the-historic-minis...
Thoughts on the Reformed faith, preparation for ministry, and doing all to the glory of God.
