I know exactly what he's saying, that's why I no longer buckle my seat belt, look both ways before crossing the road, or researching an investment before putting all of my money into a deal.
But those actions may result in death or financial ruin. Are you equating having a child with those?
Flawed analogies. Pregnancy is a part of the healthy, natural, and life-giving process of sexual intimacy in marriage.
Taking safety precautions, or prudence in investments is not the same thing as preventing something healthy, natural, and life-giving.
If you have a broken seat belt, or you can't see the road, or you cannot research and investment....you refrain from driving, crossing the road, or investing.
If you cannot afford kids....you refrain from getting married and having sex. End of story.
