I've heard that argument before and I even believed it for a while, until I started looking into what worship really is. The problem with that view of worship is that we end up calling worship whatever we feel we doing "for God" that measures up. In other words, we become the measure of what is right and how well we are doing.

Trust the past to God's mercy, the present to God's love and the future to God's providence." - St. Augustine
