Then the sons and daughters will reach twenty years of age and give birth to your grandchildren. And so on. The lineage has to be connected with the woman, go through the woman for eternity. Without children, it cannot continue for ever. If you want love you must have a partner for it to last into the future.
Woman has the position of the master.
If husband and wife do not have children, then, eternally, they cannot develop a heart of love through loving them. Some people do not know who the father of the child they are carrying is. Then they have an abortion. How miserable a situation. You have to have God's true love and tradition.
