Sadly, too many leaders consciously or unconsciously link their own careers and reputations with the gospel they proclaim and the people they serve. Slowly, unnoticed by all but the most discerning, defense of the truth slips into self-defense, and the best interest of the congregation becomes identified with the best interest of the leaders. Personal triumphalism strikes again, sometimes with vicious intensity. It is found in the evangelical academic who invests all his opinions with the authority of Scripture, in the pastor whose every word is above contradiction, in the leader transparently more interested in self-promotion and the esteem of the crowd than in the benefit and progress of the Christians allegedly being served. It issues in political maneuvering, temper tantrums, a secular set of values (though never acknowledged as such), a smug and self-serving shepherd and hungry sheep.
We have much to learn from Paul. When in our hearts (and not merely in our verbal piety) our aim before God is to strengthen other believers, not to defend ourselves, we will not only succeed in revitalizing the church by our sacrificial ministry and example, but we shall also strike a powerful blow against the demonic heart of triumphalism, which is self in another guise. And if, with Paul, we sometimes face believers who completely misunderstand our motives, then at least we may be confident, with the apostle, that we have been speaking in the sight of God as those in Christ, and that the attacks may reveal more about the attackers than anything else. May God raise up many Christian leaders whose passion is to build up the body of Christ.
