Verse 10 seems to give the foundation of holiness; verse 11 gives the spirit of the evangelist, their disposition, you might say. This is challenging and interesting.
In the same way the preacher should speak to the people. He is trying to reach people. He is not just giving an exposition. He is of course expounding the Scripture. He must do that, but he is not just speaking as though there was a glass bubble around the pulpit, and as long as we explain it all and unfold it all, that is all that is to be done. No, there are people there, and the people must feel that it is for them, and it must be applied to them. And they must be in mind and all their conditions and circumstances must be helped and comforted and addressed. So there must be a connection. Some preachers do not get it and their congregations never feel that they are in mind, that their needs are being met, that their circumstances are being considered and helped.
What are we like as fathers with our children? In verse 7, the apostle Paul has already said, ‘We were gentle among you, even as a nurse.’ He has in mind a mother, a nursing mother, and now he has got the father as an example. Do fathers take sufficient interest in their children? It is no good a father, or a mother come to that, being a good reprover if you have not first of all been a good friend, if you do not follow the interests of your children. Not in an overbearing way, not crushing their spirit, not taking over their life, but nevertheless taking an interest, and a close interest and even a responsibility. And if it is not done on the positive side with friendship and with encouragement, you have got no currency with which to give effective reproof, else all one does is stir up resentment and hostility. Even in a pagan society among the Thessalonians, Paul could assume that many typical fathers were interested in their children and concerned for their children.
