Reflections: Sphere of Ministry

In light of recent blogs about reconsiderations, revisions, and second thoughts related to our Guiding and Defining Ideas illustration, here’s an additional reflection having to do with ministry scope. 

Reflection #6: Sphere of Ministry
When the apostle Paul wrote about the scope of his ministry, he used phrases like “proper limits,” “field God has assigned to us,” “our area of activity among you,” and “another man’s territory” (see 2 Corinthians 10:13-18). One translation refers to this as his “sphere of ministry.”
Some Navigator Missions have a very clear target audience. For instance, if you are on a college campus and see a 20 year old with a backpack, then he or she is probably a candidate for Collegiate Navigators. Similarly, if you see someone in a green uniform on an Army base, then that person is a likely candidate for the Navigators Military. On the other hand, if you see someone on the streets of your city who lives somewhere, works somewhere, and goes to church somewhere, which Lifelong Laborers Mission should connect with him or her?
I expect the four Lifelong Laborers Missions will have some overlap in our spheres of ministry. Let me illustrate it this way. As one drives west into Buena Vista, Colorado, before you stands majestic Mt. Princeton. Below timberline it is a single mountain, but above timberline it has three distinct peaks. I think of the Lifelong Laborers Sphere in a similar way. We will have much in common, but we each have our distinctives. I have tried my best to articulate the distinctives of Neighbors in these blogs by unpacking our Guiding and Defining Ideas.
As time goes on, I’m sure it will become clearer that the Navigators Church Ministries focuses on church-based strategies and laborers in specific churches; the focus of Navigators Workplace is on workers and workplace strategies; the focus of I-58 Navigators is on specific areas of our cities and specific socioeconomic groups; and the focus of Navigators Neighbors is on families and relational networks, both near and far. 
You, also, have a sphere of ministry. How do you describe it?
