Here is what David thinks about all this:
The indicators of calling are spiritually discerned. If someone is called they would know it in their spirit. For others to recognize the call - in particular a very young person (IE: King David) - it would have to be revealed by the Spirit.
I teach about being called in our 5-Fold School of Ministry. Here are some of the points I believe are the building blocks of "calling.".
- Ministry is not a vocation.
- Ministry is not a position.
- Ministry is not a title. (I think that some folks have concentrated on the "office" and not on the role.)
- Ministry if filling a God-given role in the church.
- Those who don't recognize their call are often in religious structures that do not permit, or recognize the role they are called to. There is no one to model it, or a lack of teaching. (The very reason we did the 5-Fold School)
- Intimacy with God defines our call (or the lack of it) I likened it to salvation. There is a point where we cross the line (called), however; we have to work it out and mature.
- Relationship also helps define our role. Paul was in relationship with Timothy and Barnabas. Those relationships helped define the role that he was called to. The same was true of Phillip the evangelist.
- The fruit of ministry confirms a person's role in the church. IE:
The apostle's fruit is sound doctrine, tasks and teams.
The prophet's fruit is revelation, focus on the living word.
The evangelists fruit is salvation and the watering of the saved.
The pastors fruit is is the healing and wholeness of people.
The teachers fruit is imparting the knowledge of God,
They are the equippers for all other roles in the church.
The elders fruits is teaching, and corporate healing.
The deacons fruit is service.
Those that are called often go through a process:
-1 The Call (Hearing God)
-2 Submitting to Leadership (Learning to be obedient)
-3 Trained through Trials and Testing (Maturing)
-4 Desert Experience (Doing the right thing when no one is looking.)
-5 Reentry into the Church (Doing well in the little things, being a servant.)
-6 Appointment by Elders (Public recognition of the call)
I believe intimacy with God is the key. If we cannot see what the Father is doing, it is going to be really tough to do it.
