People come to church to encounter God. A good worship service is transcendent; it helps people detach from this present world to connect with the divine. But when traditional churches try to be contemporary it usually comes across as forced, stilted or artificial. This dissonance jerks people back into the mundane world. Worshippers focus on the distraction instead of the Lord.
So here’s my advice to every church: be who you are. Do what you do well – and do it over and over. If you want to innovate, do so within the bounds of your culture.
