Yes, the Church is for everyone, but the style or gifting of your particular local congregation may not appeal to everyone. If you try to appeal to everyone, you are more likely to appeal to no one. So if someone is looking for a rock and roll style Christian music service yet you sing hymns, he or she might be better off attending another church. The competition for churches is not other churches, but Satan. As long as people are going to church somewhere, you have won. Therefore, you need to do your homework, stop making excuses and figure out the best way to communicate to the local people walking in your doors (or find out why they aren’t walking in the door).
The great Christian philosopher Francis Schaeffer speaks of the Church’s challenge of meeting the unique demands of its age. This means that in every era the Church faces new competition for the hearts of people. It is incumbent upon each generation to define and meet any challenge to knowledge of God.
"We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ." (2 Corinthians 10:5)
You challenge is to determine what influences your particular church body is opposing and how best to face them in a modern context. Putting together a marketing plan is part of the process of effectively reaching your community.
