There are basically two kinds of churches in our modern-day world: the comfortable church and the great commission church. In the comfortable church, the people, and the organization, exist within a comfort zone in which they are not in any way threatened. in the great commission church, the number one priority is spreading the gospel of Christ no matter what the cost.
The majority of churches today are comfortable churches. They talk a great deal about the spread of the gospel, they do studies about it, they even give money toward getting it done, but they never really do themselves. In the comfort and safety of their four walls the gospel is proclaimed, but the society in which they exist is pretty much unchanged.
The great commission church is consumed with getting out the gospel, beginning in its own community. The life of those on the inside regularly intersets with those on the outside. Sadly, it is much more difficult to get those inside the church mobilized than it is to get those outside the church evangelized.
