The necessary element in Paul's counsel is that we be spared the type of added familial distress found in times of persecution. The list could go on. These are the types of distresses that Paul wants believers to avoid.

If we can see how these principles work together in these circumstances, then we should have no difficulty in seeing how they would provide a similar basis for temporarily delaying childbearing.
