Our culture and society have fully embraced a fairytale perspective of marriage that is based only on the emotion of love, but that backfires because when the love runs low, it doesn't usually result in "happily EVER AFTER." When we look at what God says about marriage and how He feels about it, it becomes obvious that He meant marriage to be something quite different. God views marriage very seriously, and so should we.
Marriage is about staying together.
Malachi 2:13-16
