Ministry is a gift, its a calling from the Lord. In Ephesians, God has appointed people in His church to administer the Church, to build up the body and equip the saints. Paul lists these “Gifts”, which can include many aspects of the body.

11 And He Himself gave some to be apostles , some prophets , some evangelists , and some pastors teachers and , 12 for the equipping of the saints for the work of ministry, for the edifying of the body of Christ, 13 till we all come to the unity of the faith and of the knowledge of the Son of God, to a perfect man, to the measure of the stature of the fullness of Christ; Ephesians 4:11-13

10 As each one has received a gift , minister it to one another, as good stewards of the manifold grace of God. 11 If anyone speaks , let him speak as the oracles of God. If anyone ministers , let him do it as with the ability which God supplies, that in all things God may be glorified through Jesus Christ, to whom belong the glory and the dominion forever and ever. Amen. I Peter 4:10-11
