Eph 4:11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; Eph 4:12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: The pastors job of “perfecting” is similar to the fisherman’s job of mending their nets. The Greek word being the same as well. Just as a fisherman who doesn’t mend his nets will not only lose fish and eventually his net will tear worse and worse. The pastor must mend to those that God has placed in the fold or he will lose them and the congregation will grow worse and worse. For His glory!
