That's the truth. I don't really care what "style" of worship you have - whether it's amped-up praise and worship, a capella singing, or traditional hymns banged out on an out-of-tune piano. What does the preacher SAY? The rest is, for me, more or less irrelevant. I get far more out of the sermon than I do out of the praise and worship portion of the service.
My personal taste is for the old Hymns and Psalms. They just seem to have more "meat" to them than a lot of the contemporary praise & worship music. To me, it's the difference between a 16oz Porterhouse and a bag of Pixie Stix candy.
"Be thou my vision, O Lord of my heart.
Naught be all else to me, save that Thou art."
versus
"We love you Lord, we love you, we love you" (repeat 8x)
But, I digress. If the preaching is sound and truthful, God's work will be accomplished:
"For as the rain and the snow come down from heaven
and do not return there but water the earth,
making it bring forth and sprout,
giving seed to the sower and bread to the eater,
so shall my word be that goes out from my mouth;
it shall not return to me empty,
but it shall accomplish that which I purpose,
and shall succeed in the thing for which I sent it." ~Is 55:10-11
