There is no question, in the Bible, or in the history of the church, that love is the center of the Christian universe. It is one of three things, along with faith and hope, that lasts forever, and is the greatest of the three. It is the dynamis, the power that moves the world. It is the basic magnetism holding everything together: God's love for us, and our love for him and for each other. Just as carbon is the universal element of physical life, love is the universal element of spiritual life. "If I have not love," Paul said, "I am nothing," and he meant that literally. "Nothing!" Matthew Henry said love is "the spring and fountain of all the rest." But the word is much abused today. Love has been cheapened down to a Pavlovian response. Love has a million impostors, and many things that aren't love try to pass for it. How can we tell? What's the difference between Hollywood love and the love of God?
