Darin Hufford has done a wonderful teaching that in my opinion hits the mark. I think the following excerpt really makes clear the fact that the church has gotten off track on the subject of worship and what worship really is. If you're interested, you can read the entire blog on his website.
"Worship in the Old Testament times was very different than it is in today's world. . . Because sin had not been atoned for and God could not live inside their hearts, they would worship Him together from afar, by sacrificing animals and going through lots of prescribed rituals. When they praised God, He could actually come down and "inhabit the praises of His people", but that's about as close as He could get. Worship at that time had nothing to do with the people's love for God; it was a commandment He gave when He took them as His people.
In the New Testament times, sin has been atoned for and God can now live in our hearts. God hasn't changed from the Old to New Testament, however THINGS have. New Testament worship is actually a "consummation" of a marriage relationship between the individual and God. In other words, it is not a corporate event, and for Heaven sakes we don't need a leader! Could you imagine if I were to allow a man to enter my wife's and my bedroom with a megaphone, stand over our marriage bed and give us directions? It sounds pretty silly doesn't it? This however, is a picture of what "worship leaders" do today, in churches all over America. Worship for the New Testament believer is personal and private. That is why New Testament references to worship say things like, "sing and make music in your hearts." Old Testament worship was exterior and New Testament worship is interior. Jesus underscored this principal over and over in His ministry."
