Bill Barnwell has written an important article called Christians and Cultural Mediocrity. Some quotes:
He challenges us to rediscover our historical roots of being influential cultural movers and shakers in the world where we live.
Historically, Christians contributed significantly in many areas of scientific advancement, the humanities, and literature.
It seems that in the quest for cultural advancement, many Christians are being, well, left behind.
Technologically, plenty of churches are still apparently learning that there is such a thing as the World Wide Web out there. Church websites are notoriously poor and lack regular updating. Outside of a couple different Christian publications and organizations, Christians on a whole have not yet found a way to use the web to meaningfully engage their communities and the culture at large.
In terms of the economy, there have been little economic or technological innovations by Christians in recent years.
