Ephesians 4:11-12 (New International Version)
11It was he who gave some to be apostles, some to be prophets, some to be evangelists, and some to be pastors and teachers, 12to prepare God's people for works of service, so that the body of Christ may be built up
The job of the ministry is to not actually do the work of ministry but to prepare Gods people for works of ministry. Now I am not saying this in a Pharisaical way where all the pastors just tell what to do and not do. But they are actually out doing the work of the ministry and also having people do the work of ministry.
It is the pastor’s job to prepare Gods people for works of service not to actually do all the works of service.
See what happens when the Disciples realized this:
Acts 6:1-10 The Choosing of the Seven
1In those days when the number of disciples was increasing, the Grecian Jews among them complained against the Hebraic Jews because their widows were being overlooked in the daily distribution of food. 2So the Twelve gathered all the disciples together and said, "It would not be right for us to neglect the ministry of the word of God in order to wait on tables. 3Brothers, choose seven men from among you who are known to be full of the Spirit and wisdom. We will turn this responsibility over to them 4and will give our attention to prayer and the ministry of the word."
5This proposal pleased the whole group. They chose Stephen, a man full of faith and of the Holy Spirit; also Philip, Procorus, Nicanor, Timon, Parmenas, and Nicolas from Antioch, a convert to Judaism. 6They presented these men to the apostles, who prayed and laid their hands on them.
7So the word of God spread. The number of disciples in Jerusalem increased rapidly, and a large number of priests became obedient to the faith
Peter and the leaders were actually doing the work of ministry--which in turn hindered the growth and in turn--they realized they had to choose some men to do the work......so in verse 7 it says the Word of God spread.
