New Testament
Ephesians 4:11-12 "And He gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; (12) For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:"
Some years ago I was discussing this verse with a small group of fellow-believers who were fellowshipping after our Sunday evening church service. I mentioned a study I had done on the meaning of the word "perfecting" as it is used in this passage which, according to Vine's Expository Dictionary, carries with it a sense of "completely furnishing" something or someone for a particular purpose.
Our pastor, who had been in the navy, commented that he knew of this and likened it to a naval expression. He informed us that when navy ships are fitted with guns they are said to be "furnished", and he went on to explain his thoughts on why the saints comprising the church needed to be furnished with apostles, prophets, evangelists, pastors and teachers.
At the time I pictured a fully armed warship with large guns extending from a number of turrets and understood the point being made was that of the purpose of these five God ordained offices as a protective covering for the ministering saints as they build up the body of Christ.
With regard to pastors, by definition they are to watch over the flock and provide the sheep with good pasture, also making sure they are safely watered. By promoting the spiritual health and growth of the saints in their care, pastors can be sure that the work of ministry will not be neglected and as a result the church will be built up.
However, sometimes the shepherd and the sheep don't get along too well and both become stressed, frustrated, and impatient, or even worse, hostile towards each other. There is often fault on both sides, but it is well to be warned that the church can be a dangerous place as Paul pointed out.
Acts 20:28-30 "Take heed therefore to yourselves, and to all the flock over which the Holy Spirit has made you overseers, to feed the church of God, which He has purchased with his own blood. (29) For I know this, that after my departure grievous wolves will enter in among you, not sparing the flock. (30) Also from your own selves will men arise, speaking perverse things, to draw away disciples after them."
