John was reaching here

In the evening and the following morning I brought strange things to the ears of many in Manchester, concerning the government of their families and the education of their children. But some still made that very silly answer, "Oh, he has no children of his own!" Neither had St. Paul, nor (that we know) any of the apostles. What then? Were they therefore unable to instruct parents? Not so. They were able to instruct everyone that had a soul to be saved.
