What does our worship say about our theology?

In studying the second commandment I kept thinking about how our worship portrays our theology. Do we put an emphasis on service or on worship (check the announcements)? Do we place a high value on Scripture and Scripture reading? What does our music say about our theology? Is it God centred or man centred? Do we place a high priority on the preaching of the Word and in the preaching is it Biblical or topically centred? And finally our prayers, do they focus on man and his needs or on God and His glory? Just wondering.
