As our series on worship continues, we consider the rule for worship - what is called the Regulative Principle. A principle that comes from the Bible - which teaches that whatever is not commanded is forbidden in worship. In this sermon we are exhorted to hear of the heart of the principle and also discover how the principle glorifies God and protects the conscience of the worshiper. Preached on Sabbath PM 05/02/21. Of the Regulative Principle of Worship… I. Its doctrine. II. Its heart. III. Its King.
