It might seem strange to put a Kurt Vonnagut quote in a preaching blog, but I love this quote. It came from the last interview he gave before he died (which was last April). And while it may not deal directly with preaching, I think it deals directly with the LIFE of the preacher.
“I’ve been drawing all my life, just as a hobby, without really having shows or anything. It’s just an agreeable thing to do, and I recommend it to everybody. I always say to people, practice an art, no matter how well or badly [you do it], because then you have the experience of becoming, and it makes your soul grow. That includes singing, dancing, writing, drawing, playing a musical instrument.”
