This marriage relationship is looked at in more detail in the first paragraph of Pink's writing. The quality of a marriage determines how the roles of father and mother will be filled and significantly impacts the entire lives of sons and daughters which will be born into that marriage.
I considered merely posting a link to the quote, but I wanted to make sure that you read it! In an effort to make it more easily accessible, the decision was made to copy the quote over to my own blog.
It is perhaps a trite remark, yet nonetheless weighty for having been uttered so often, that with the one exception of personal conversion, marriage is the most momentous of all earthly events in the life of a man or woman. It forms a bond of union that binds them until death. It brings them into such intimate relations that they must either sweeten or embitter each other’s existence. It entails circumstances and consequences that are not less far-reaching than the endless ages of eternity. How essential it is then that we should have the blessing of Heaven upon such a solemn yet precious undertaking, and in order to this, how absolutely necessary it is that we be subject to God and to His Word thereon. Far, far better to remain single unto the end of our days, than to enter into the marriage state without the Divine benediction upon it. The records of history and the facts of observation bear abundant testimony to the truth of that remark.
Even those who look no further than the temporal happiness of individuals and the welfare of existing society, are not insensible to the great importance of our domestic relations, which the strongest affections of nature secure, and which even our wants and weaknesses cement. We can form no conception of social virtue or felicity, yea, no conception of human society itself, which has not its foundation in the family. No matter how excellent the constitution and laws of a country may be, or how vast its resources and prosperity, there is no sure basis for social order or public as well as private virtue, until it be laid in the wise regulation of its families. After all, a nation is but the aggregate of its families, and unless there be good husbands and wives, fathers and mothers, sons and daughters, there cannot possibly be good citizens. Therefore the present decay of home life and family discipline threaten the stability of our nation today far more severely than does any foreign hostility.
