I think i have to say i disagree a little.... I believe the job of the pastor is to guide and encourage each believer to be obedient to God's Word and to walk in God's ways. And to preach the uncompromised Word of God in love. It's to be a shepherd like our Lord shepherds His flock...and yes sometimes that may make people uncomfortable initially...however the encouragement brings them peace also.Amen my brother. The job of any preacher is to make his congregation "uncomfortable".
Jesus operated in the office of a preacher just as much the other gifts. And should always be our example
