Air conditioning or prayer?

Sometimes you come across something that makes you ashamed. Happens to me a lot. Don't know what that means. At any rate, over at the 4HisGlory website, there's a fine article entitled Air Conditioned Churches or Perseverance of the Saints?
and the author recounts hearing two urgent prayers at the seminary he attends. One asked the Lord for air conditioning so that things won't be so uncomfortable at church Sunday. The other prayer lifted up the remaining living Korean missionaries, the ones that the Islamic heathens have not yet murdered. Which matter is more important to us?
Which one is more important to me? How many churches around the world will even think of these brave missionaries this Sunday, or even on a Wednesday evening?
