Worship

Isaiah 6 sets forth an example of true worship. Read it or something. Here's what I see:

1. True worship must include confession of sin.
   Verse 5:
   "Woe to me!" I cried. "I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the LORD Almighty."
2. True worship must include cleansing from sin.
   Verses 6-7:
   Then one of the seraphs flew to me with a live coal in his hand, which he had taken with tongs from the altar. With it he touched my mouth and said, "See, this has touched your lips; your guilt is taken away and your sin atoned for."
   
3. True worship must include obedience to the call to serve.
   Verse 8:
   Then I heard the voice of the Lord saying, "Whom shall I send? And who will go for us?"
   And I said, "Here am I. Send me!"

Maybe it doesn't really matter if we sing choruses or hymns at church. So what's all the fuss about?
