I think we can serve as different parts of the body of Christ in different circumstances.
In some groups, one can be called to lead and be the head. In other settings, the same one may be needed as the hands and feet to bring the ideas to fruition. Sometimes one does best to receive information and process it, like the stomach. And every now and then, one finds oneself in the role of the digestive tract, helping the whole group by filtering out what needs to stay and what needs to go.
In what ways have you witnessed one being called to serve the church body?
