God chose to set the example of partnership in missions by working with and within humanity to accomplish His redemptive plan. Jesus called on us to carry out the Great Commission through his incarnational or 'missional' example.
In recent history, there are individuals and a scarce few churches that have exemplified the missional example of Jesus. In my opinion, there is no Christian denomination in existence today that embodies the missional church.
There has been a resurgence of the missional church. But missional people and missional churches operate under the shadow of the institutional Church. The institutional Church, and the denominations within it, have done a disservice to many Christians in creating and teaching a "corporate America" mindset in doing the work of mission.
The denominational stockholders are encouraged to invest in the local church. The local church, in turn, pay a franchise fee to the denominational mission institution or "sending agency". Professional missionaries are screened and hired by the sending agency and are then supported as the sales force of their denomination. They come home regularly to give reports. The sending agency of the denomination publishes their annual report in the hope of increasing their revenue base. The institution feeds the institution. Some mission work takes place, for sure, but effective mission work suffers.
There is need for a wholesale change in denominations to adopt missional thinking. So that missional people don't come off as elitists or whiners, it's important that missional people are an example to the institutional church by modeling partnership in mission work. A wholesale change in thinking by a denomination will take many years of influence, so that means that people that have recaptured the missional thinking of the early Church should work with their respective denomination while partnering with others to accomplish the Great Commission.
So what if you're like me and you just can't do the denominational thing anymore? Keep some of your denominational contacts. Then look for like-minded people to partner with in missions. There are plenty of movements out there, just keep your ears and eyes open. Above all, keep being missional.
