The primary objective of marriage is for companionship and not child bearing. Although child bearing is also one of the reasons for getting married but should not be seen as a major reason for marriage. Children are blessing from God. Any marriage that have not been blessed with children the both partners should leave happily believing God for a miracle and never see it as a reason for hatred. With or without children, man love and cherish your partner same also to the woman respect your partner
There is a disclaimer that no one want to put birthday by wedlocks but legitimately married before birthday. This is so children can always receive health and responsible cares from their parents because a lot of children has been perished due to the unreadiness of parents bearing children. So it is prioritized that children should be welcomed in an agreement of a husband and wife as one family (marriage) so it comes their responsibilities for the well-being of the children.
Every home needs to breed their own offspring to keep the lineage going from generation after generations but does not mean a call of disaster when your family was unable to bear a child because it is nature that has it gifted and not just by a man.
