What is worship for?
in the Scriptures (and through church history) worship was intended to be worship. It was aimed at God, in adoration and supplication, not at attracting non-believers, or even at giving fellow-worshippers a good worship experience. This focus on God was the case until very recently; now our immersion in a consumer economy has led us to think of everything in terms of appealing to potential customers. We are so mentally saturated in advertising that we have come to think of ourselves and our faith as products that need to be persuasively sold… In the Scriptures worship is directed to God, not to anyone on earth, not even to other worshippers. It is certainly not directed to people who don’t yet love and respect our Lord; in fact it should be expected that our worship will be unfamiliar, perplexing, and mysterious to them. In worship we focus on Him, and those who don’t yet see Him just won’t be able to grasp it. It’s appropriate that outsiders not understand what is going on. It’s appropriate that they don’t immediately get it. But they can see that the worshippers take it very seriously, and that they really believe God is present and hearing their prayers. That kind of worship is in itself powerfully compelling, and has its own magnetic pull.
