Perhaps it has not escaped your notice that the lust for power did not die with Simon Magus. We are called to be shepherds of the flock and not tyrants. Following the example of the overseers in Egypt leads to a mass exodus and the spoiling of our goods. Such preachers are nothing but wild boars who destroy the vine and ought to be avoided like the plague. The Achilles' heel of many a preacher is not the great or gross sins which we think are apparent to all but the latent sins of the spirit.
Spiritual pride is ruinous to Christian character.
Self examination is good for the soul, however, it is also costly. Even Paul was haunted with the fear of disqualification from service, but of course, not from redemption. Disappointment in results or lack of appreciation for effort is too often followed by bitterness of spirit. To throw the blame for lack of success on the Lord's people is tantamount to advertising our lack of spiritual maturity. The New Testament in speaking to us of the Christian ministry, uses a variety of illustrations simply to show how diverse is this service under one master.
