I agree.
Of course the church shouldn't turn people away because of how they look. And I've rarely heard of that actually happening, while I've much more often been in churches that welcomed people no matter what.
But how do those on the "outside" feel when they see a congregation leaving church, all in their Sunday best, and looking very conformed? Not that there's anything wrong with that, but might the tattooed biker, the kid with a punk hairdo and goth attire, the woman whose only dress barely skims the top of her thighs - might they not look at themselves and judge that they don't fit in? Might they not be afraid to encounter the condemning stares they expect will be there, whether they actually would be or not?
I don't actually know what goes on in people's minds.
But I've been in a number of churches that attracted people like that. Now, again in being honest as I made the distinction in my last post, these aren't (in my experience) light-show churches. Those are another category. These are usually found in old movie theaters, abandoned strip malls, and the like. The building rarely looks like a church. I've never seen elaborate stage shows, though loud music is common. There often is no overhead, and if there is, they usually are nowhere near as technologically advanced as PowerPoint. The only amenity is usually a church nursery, though they might offer coffee and refreshments before the service. The pastor usually looks like a slightly-cleaned-up version of his congregants, and has a friendly and uncalculated manner.
I have experienced a true presence of worship in such services, but they are usually too loud and too rock-and-roll for my taste (and I enjoy contemporary Christian music). The teaching is often quite insightful and Biblical. It seems these pastors are actually LESS afraid of offending their congregation than most other types of churches.
This is the one part of the churches sometimes labeled "seeker" that I am praising.
Not my style, but they serve their flocks.
(And btw, I do agree that Salvation is God's business. I believe we can share the truths we have, but that's about it. You, I, and yes the Apostles were unable to "save" anyone.)
