The Regulative Principle of Worship sounds ominous, but really it is simply worship dialogue–God speaks and we His people respond. Our worship is vertical and not horizontal, that is, we do not perform for one another, but corporately, as one people, we worship God. Because we have Jesus as our High Priest, we do not need earthly priests to intercede for us, but we can respond directly to our Heavenly Father in worship. Our Advocate in heaven, the Lord Jesus Christ, mediates on our behalf and makes our worship suitable to our Holy God.
