‘But I would have you free from cares. He who is unmarried is careful for the things of the Lord, how he may please the Lord. But he who is married is careful for the things of the world, how he may please his wife.'
Here Paul comes to the crux of the matter. His recommendation of celibacy has nothing to do with the fact that the flesh is thought of as sinful, or that asceticism is seen as making a man spiritual, it has to do with practical reality. He wants them, in view of the emergency times, to be free from other cares. The married person has cares and responsibilities that a single person knows nothing about. His wife will expect not to be neglected and will need her wants seeing to. This will partly depend on whether he has married a wife as dedicated as himself, but even if he has, life is such that problems can arise that take up his time and attention that would not have arisen if he had been single. He must provide a home for his children. He must watch over them and care for their needs and wants. And we could go on.
But it is clear that a married man will have certain distractions which may well prevent his hundred-per-cent attention on what would please the Lord given no distractions. Of course his proper attention to his wife and family pleases the Lord, and in return they provide him with support, joys and experiences beneficial to his spiritual life. He may well be a stronger Christian because of them, and if he is a man of strong sexual desires he almost certainly will be. But compared with the single man he has a considerable number of things that he must watch and control in order to be the best he can for the Lord that the single man knows nothing about. His full dedication to God's service is therefore all the more difficult. He has so many distractions.
On the other hand we can argue that in the long term it is Christian families who have been the mainstay of the church through the ages. And we would be right. But if we are honest we can see that Paul's point is valid. There will always need to be those who are so free from distractions that they can go anywhere, and do anything, without fear of the consequences for loved ones. And married men who have sought to behave as though they were as free as single men have often thereby brought great distress on those whom they should have been caring for. How difficult it is to tread the fine line between obedience to the Lord in service and obedience to the Lord in family responsibilities. And this the single man knows nothing about (except with regard to close relatives).
But we must note here two things. Firstly that Paul knew very well that a large proportion of men would, in the light of his advice given earlier, need to marry. No one would have been more surprised than he if all the Corinthians had become celibate. What he was seeking was the select band of those who would be available for service of any kind. And secondly that he does not in any way indicate that such people are more spiritual or more deserving than those who are married. His point is practical and not judgmental.
