From the beginning to end, the Holy Scriptures have a very positive view in bearing and raising children.
(Genesis 1: 27-28) God's desire for his people to bear more children is seen in several other passages. ( Ps.,127:3) ( 1 Tim. 5:14).The responsibility for training their children fall upon the parents, not on "society " and not in the government.( Deut. 5:4-7) The benefits that a married couple brings to their children are numerous. Children who live with their own two married parents have significantly higher Educational achivement, better economic standard, better physical and emotional health, and more likely to live according to higher standard of integrity and moral principals.
For these and many more reasons marriage between a man and women is the basic building block of any stable society, and is essential to the continuation of a healthy, stable society.
