In a conversation with another believer the term Kingdom Outpost came up. Our tribe is a satellite location of a larger congregation. We are a part but separate. We have our own personality, we will never be a cookie cutter copy of the Big Church, nor would we want to. Although they have many resources which we can utilize and they support us financially, we are different. We aren't a microcosm, we are an appendage.
To be an outpost of the Kingdom is to accept the form of the gifts and graces that God has provided in your gathering of believers. Not every "church" is the same. Not every outpost has the same needs or the same flavor. This group may have a heart for missions, this group might not have designs on bible study and growth for adults, this group may have everything that we define as a church except no children's ministry. This one exists for prayer and worship. In the Kingdom, we have no cookie cutter definition of "church". We meet, we learn each other's gifts (no surveys needed- we do life together and the gifts become evident) and leaders rise to the top because the Holy Spirit makes it obvious. There is fruit we bear, not titles we hold. An outpost does not require a name, or a building to define it.
So it is with small groups of believers meeting in homes- you have an organic expression of the church of Acts without the persecution (so far) and it is not any more complete than it's members give what God has given them to the fellowship.
Our net has a few perceived holes in it- we don't have a youth ministry, we don't have a place to do a free-store yet. Our Big Church has these things in spades. I would say that when the opportunities line up with the gifts and desires, these things will come to be, until then we should follow the direction our present gifts lead us and leave the other things be.
I have a friend in a nearby city who has turned his home into a House of Prayer they have a wall on their front porch covered with prayer requests, people stop by and can get prayer 24/7 or just leave a note pinned to the wall. There is a sign in the front lawn. That is all he does. Prayer. Yet what a great thing to be this kind of Outpost. Apparently, there is a great need and he is being obedient.
Other friends do free marriage counseling, host bible studies, house recovering drug and alcoholic abusers, teach financial management, provide child care to single moms. These things are all Kingdom Outposts- ministries in homes- small groups of believers connecting in meaningful ways. We are pioneers of a different sort.
