When we consider church attnendance, we have to throw out our assumptions...and we (meaning "we" church goers) have a lot of them. We assume that people believe in God or want to believe. We assume that people want to pursue truth and that we possess it. We assume that coming to our particular church is the most natural thing to do. We assume that if a true seeker does enter our doors that they will easily understand what we are doing, why we are doing it and understand how it all relates to knowing God.
I agree that it is safe to assume that people have at least a minimal faith/belief in God. Polls have continually indicated that throughout the years. The church has warned of our nation turning away from God but that hasn't happened. There is a greater interest in spirituality than ever before. But people have been turning away from "our" kind of God - the Chrisitian God. And why is that? Erwin McManus puts it well...
"The biting truth is that this country in not rejecting spirituality but Christianity. The indictment that we must receive is tha the Christian faith as we express it is no longer seen as a viable spiritual option. Masses gave the church a try and left wanting. We accuse them of not being willing to surrender to God; they accuse us of not knowing him. People are rejecting Christ because of the church! Once we were called Christians by an unbelieving world, and now we call ourselves Christians and the world calls us hypocrites. Is it possible that it wasn't the nation that was becoming dangerously secular but the church? We were neither relevant nor transcendent. We have become, in the worst of ways, religious." an Unstoppable Force, p. 29
The key to this indictment is in the way we express our faith. It may make sense to insiders, people who know the "codes". But to outsiders it comes across as rules and meetings. Who needs that? People are looking for relationship and transcendance.
I say all this to underscore the fact that a big reason that people don't want to come to church has nothing to do with them and everything to do with us! People are looking for something to give their life to, even die for and our message is not compelling. We have drifted far from the faith of the first disciples. So... before we are quick to point the finger at the unchurched, let's look in the mirror and ask where we've gone wrong. That level of honesty alone is attractive.
