The Law of Pursuit
When couples first begin to date, they typically work very hard at impressing each other. Careful planning goes into preparing for each date, behaving in a pleasing manner while together, saying the right things, and so on. As time passes and they reach a point of being comfortable, they tend to stop working at the relationship and begin taking it for granted.
Many marriages are in the same position today. The spouses no longer work at pleasing each other; instead, they take one another for granted and try to coast through a marriage void of romantic love.
When God instructed man to "cleave" unto his wife, He knew that the secret of staying in love is work. God's command in Genesis 2:24 is for a man to zealously pursue his wife and to energetically cling to her for the rest of his life. If you will make the decision to pursue your spouse with energy and diligence, you will quickly find it is a labor of love with satisfying results.
