What if Church were fun?

I know I'm just 24, but I am really fascinated by the crisis that some people experience at midlife because it seems to offer an opportunity for a new beginning. Sue Monk Kid has written an excellent book tracing her journey through midlife called When the Heart Waits. In the beginning of this book she introduces the concept of "Orphaned Voices", which represent unlived parts of her life. More specifically, she says, "They seemed to speak for all the unlived parts of me, and they came with a force and dazzle that I couldn't contain. They seemed to explode the boundaries of my existence. I know now that they were the clamor of a new self struggling to be born." So, I started thinking about "Orphaned Voices" in my life that are struggling to be born. The first question that popped into my mind was, "What if Church were fun?" As a pastor, I look out on my congregation sometimes during worship and they look bored, tired, unengaged, and sometimes downright miserable. Instead of breathing a sigh of relief when church is over, what if our youth hated leaving church the way they hate leaving their best friend's house? I agree with some people's concern that worship should not primarily be entertainment, but I've never understood the mantra that "Church isn't supposed to be fun!" My sould breathed a sigh of relief when one of seminary professors reminded me of Zecheriah's vision of the restoration of Jerusalem:
Zechariah 8:5 And the streets of the city shall be full of boys and girls playing in its streets.
This is my vision of heaven: Children playing in the streets.
I'm not saying that we should start playing 4-square in the sanctuary, but shouldn't our worship be a reflection of the joy, excitement, and fun of the restored kingdom of God?
