If we are willing to come out of our church enclaves and actually go into our secular neighborhoods and develop relationships, we might become shocked to learn that there has been a dramatic cultural shift occurring. Christendom no longer holds the seat of cultural influence that it enjoyed in the 20^th century.“We are definitely in a post-Christian society. This is easy to establish as most people do not even recognize biblical or church terms, never mind even have a rudimentary understanding of what they mean. At the same time, people have changed. They’re less likely to stand on a doorstep and argue with a stranger, they’re less likely to go to an event to listen to a famous speaker, they’re busy, they mostly don’t have time to think about abstract ideas, they think religious people are strange. So it is now impossible to speak widely to people about sin (for example), because few understand the term and of those that do, few really care what Christians think. Most people think that church is just a quaint building where weirdos go on Sundays, and normal people use only a few times in a lifetime (wedding, funeral, etc.).That isn’t to say that vocal evangelism is unimportant as such, just largely ineffective for most people. Which leaves Christians with a hard choice: either to stop pretending that Christianity is anything more than an intellectual exercise, or to get involved in their communities. The latter is difficult, because it means genuinely loving those around us and seeking sacrificially to serve them rather than just preaching at (or near) them.” (-taken from a post on the Doable Evangelism blog site)
