Consider this from Michael McKinley at 9Marks:

A good friend attended my church for a few Sundays. One comment of his stood out to me. He was struck by how different I was on Sunday mornings compared to the way I might be on Thursday afternoon over a cup of coffee. He wasn’t accusing me of hypocrisy (or so he said), rather he was noting an intentional shift in tone and demeanor. Whereas I’ll be sarcastic and (attempt to be) funny in personal chit-chat with a friend, I am much more reserved and measured in my preaching and leading of the church. In short, I’m much less cool.

All of that is intentional. It’s not too hard to draw a crowd, methadone clinics and brothels do it all the time. You could flash the tats and play some rock music and preach funny sermons and I promise you’ll get a crowd if you do it well. But I think if I do that, I’ve obscured Christ and drawn people to myself and my personality. I’d much rather step back, tone down my largish personality, and try to draw attention to Jesus.

What do you guys think. Should we (who may or may not be “cool”) change the way we act and talk on Sundays in our church services in an effort to get our personalities out of the way to show the people Christ? Does that imply that we are being sinful in our normal everyday behavior?

So should we cover our tatoos, flatten our spikey hair, and tuck in our shirts in an efforts to not be liked by people who come hear us for the sake of the gospel?
