Corporate Worship

In reading through the reading in Give Praise to God I realized how much it was talking about making sure you are worshipping in the correct form of corporate worship. Using the right elements and coming to God in true worship is very important. Throughout the reading I couldn't help but wonder how do you know if you are coming in true worship. The rules that Paul gives for worship are given and we can argue over and over what the correct form of worship is and our churches show the many different varieties and how people think it should go in order to get to true worship of God. I think the answer to my question came when I came to the end of the paragraph on page 48 where it says, "Because God the Spirit who wrote the Lord's command is the same Spirit who endables true worship, there can be no ultimate conflict between form and freedom, between rules of Scripture and the heartfelt expression of praise, between the precepts of worship and unfettered engagement with God." To me this is saying that if you are truely filled with the Spirit then you will come to God in true worship because he is the one enables true worship. The rules give us guidelines to follow. So now how do we know if our churches are worshipping in true worship? If it's corporate worship you can't see the hearts of all the people worshipping.
