What is our heart of worship?

Today at Calvary Worship Center, the pastor spoke on what the church is supposed to look like.  He talked on how we are the body of Christ, and Christ is the head of the body.  An interesting quote, "The body does not dictate what the head does, but the head dictates what the body does."  But what really intrigued me was when Pastor Lonnie started talking on worship within church.  He mentioned how we can become routine worshippers or that we come to church hoping that this certain person is leading worship so we will enjoy it.  He talked on how we hope certain songs are sung at church because we really like the beat of the music.  We try to find churches that we can really get into the music.  But notice how all these statements say we.  What is the heart of worship? It seems like it's not so much about God and it has become more about us!  Does God really care about the beat of the music or about what song is sung to Him?  Man looks at the outward appearance, but God looks at the heart!  Why are we so concerned about what we feel!  We should not concern ourselves with these petty issues, but get back to the heart of worship!  Worship is all about Him!!  Holy, Holy, Holy is the Lord God Almighty!!  May we not worry so much about the emotion that the songs provoke in us, but may we become more concerned with praising God with our everything!
