The Bible calls every one of us who call ourselves Christ followers:
Ministers, Priests, Servants, Slaves, Workers, Disciples...and the list goes on. Actually one word the Bible never calls us is volunteers. I think that is because if we are going to follow Jesus, if He is going to be our Lord we don't volunteer, rather we submit.
For the purpose of this form we are going to use the word MINISTER because each of us has a part to play in the Body of Christ, the Church. We are going to stick with the word "ministry". You heard that right:
everyone has a part to play, a ministry to minister in.
