...about air-con in the church
Priest: "When we cool one place, we are making another place warmer..." (making the church cooler but making the environment warmer or known as global warming...)

In fact when you think in another way, you can actually apply back the "When we cool one place, we are making another place warmer" in another version which is "we can cool the church and make the other place which is our heart warmer..." hehe...
