There is only one ministry in the church, and that is being a servant of God. God is the one who makes men and women into ministers; we do not choose it ourselves, and we are not to judge His choice. Paul suffered afflictions for his association with Christ and the preaching of the Word, but he rejoiced. Suffering is part of the process of being made into a man or woman of God.
