" A failure to love is often because of laziness. And, we all know that the failure to be loving has horrendous consequences in our world.
What is love? Did you know that when the Bible describes love, it almost always speaks of a command: husbands are commanded to love their wives; wives are commanded to love their husbands; all people are commanded to love their neighbors. Jesus spoke of love as something that people should do. This means, people of God, that love requires commitment and hard work; but, those who are lazy are seldom willing to expend that kind of energy. For the lazy people of our world, love is something that is just supposed to happen. Most popular songs on the radio make love sound like an accident, a spontaneous emotion, which can be neither controlled nor created. But love is not a feeling. You don't fall in love, nor do you fall out of love. Love is something you deliberately decide to do and to give.
The failure to recognize that love is an art requiring discipline and hard work is largely responsible for the absence of love in so many of our relationships. Nowhere is this more evident than in marriage. Too many husbands and wives are too lazy to love each other. Love becomes nonexistent and marriages collapse because most people do not work hard or are not willing to work hard to create love and build marital relationships."
