Agreed.I think that this is the difference between viewing the ministry as a calling rather than a professional vocation. But I don't think that these things are exclusive (seminary and preparation of the Spirit). God is a God of means. When the Holy Spirit calls a man into the ministry I believe that the Holy Spirit does prepare that man but often that preparation is in the form of seminary.
I'm glad you're not saying me brother, because that isn't my meaning at all. I am saying that the Christian ministry is not a profession like medicine and whilst I'm sure that seminary is the correct route for those who have the opportunity, support and/or finance to pursue it, it should not be considered necessary.I mention this only because some people (I'm not saying you, brother) have, in the past, discussed seminary as somehow separate from the preparation of the Spirit to the ministry when in fact seminary may well be the means of preparation. I agree that when God calls a man God makes that man what He has called him to be.
Here in Britain, increasingly many churches are getting smaller and smaller and they can't support their young people through seminary and can't pay a full-time Pastor anyway. The Pastor of tomorrow is likely to have done a part-time course and be holding down another job to feed his family.
