It is up to the married couple to decide if they need to control the growth of their family, because of not being able to take care of their children finically or spiritually. Deuteronomy 6:6,7 "These words that I am commanding you today must be on your heart,and you must inculcate them in your heart,and you must inculcate them in your sons and speak of them when you sit in your house and when you walk on the road and when you lie down and when you get up." Also 1 Timothy: 5:8," Certainly if anyone does not provide for those who are his own, and especially for those who are members of his household,he has disowned the faith and is worst than a person without faith." These are some of the reasons why a husband and wife would choose to limit the size of their family,.
