One of the greatest challenges marriages face today is an understanding of what love really is. What is love? The world's system, as expressed through media, entertainment, and advertising sells love as getting something, receiving satisfaction, a fulfillment of wants and desires. This idea sets marriage up for failure. If you were to substitute the world lust for love, you'd probably have a much better definition of what the world views as love. The Bible calls us to a different kind of love – true love, biblical love.
