If anyone aspires to the office of overseer, he desires a noble task. Therefore an overseer must be above reproach, the husband of one wife, sober-minded, self-controlled, respectable, hospitable, able to teach, not a drunkard, not violent but gentle, not quarrelsome, not a lover of money. He must manage his own household well, with all dignity keeping his children submissive, for if someone does not know how to manage his own household, how will he care for God's church? He must not be a recent convert, or he may become puffed up with conceit and fall into the condemnation of the devil. Moreover, he must be well thought of by outsiders, so that he may not fall into disgrace, into a snare of the devil. (1 Timothy 3:1-7, ESV)
A pastor is a shepherd for God's people in the the church. He cares for them in the midst of suffering, pain and even death. He comes to them time after time with God's Word and feeds them with Christ's Body broken and His Blood poured out for them. He confronts the man secure in self-righteousness and comforts those burdened by the weight of their own sin with the proclamation of forgiveness.
