Some persons are simply not cut out for being parents and if they are capable of realizing this of themselves and do not have children they are wise. That doesn't mean they should be condemned to living single either.
Many valid reasons exist for married persons not to have children. One is a parent having a genetic disorder that would effect their children. They may not wish to see their offspring acquire the disorder. Another is the health of the mother. The mom could possibly not be able to carry a child.. The mother may have to take medications that would cause birth defects to a child. Their income may prohibit it. They may have jobs that would severely limit their time with the children for example being doctors.
Children bring happiness to many parents. Biologically I have none nor will I ever. It wasn't a matter of not wanting it was a matter of it could have killed my wife to try. I do have two step daughters I helped raise. The preacher needs to focus his energies on more pressing matters such as stopping mothers from abortions rather than laying guilt trips on ones who simply choose never to conceive to begin with.
