Am I Called into Ministry?

Being in ministry is like being a waiter at a restaurant. Unlike other professions where you can study for them and acquire skills, being a Christian minister does not simply occur because you are skilled. Most fundamentally, in Christian ministry, God is the one who chooses those whom he calls to work in his vineyard. So the question Am I called to ministry? Can be rephrased as Has God called me to serve him and his people?
