But its not all about you is it?
No, its not all about me. As I stated previously it is about God. However, are we not to be changed in the spirit of our minds to find that which is pleasing to God (Rom 12:1-2)? While it is not all about us, it is some about us. We are to worship God. We are to learn to worship God as He designed it in Scripture. We are to be obedient to God’s Word, which glorifies Him.

So here's the bottom line for me: If its the attitude of the heart that matters most, why do we clutter our worship service up with rules and expectations?
I personally do not see God’s Word which regulates worship as “clutter.” What type of attitude, not regulated by Scripture, is acceptable to God? What you describe is more like a bar atmosphere, where everyone may do his own thing—as there are no rules or expectations. However, God does have certain expectations of us in worship and He has given us His regulations so that they may be achieved. The rules of God are there for our enjoyment because they restrict us from that which is not pleasing to a holy God.

BTW: I like the banjo.
