By this everyone will know that you are my disciples, if you have love for one another. They had it all right because love directs and informs all else. Think about it. What is peace but love that accepts the world as it is, not as it ought to be. Patience is love that persists in spite of injustice.
Faithfulness is love that believes without guarantees.
And kindness is love expressed in gentleness, while gentleness is the true nature of love. Indeed, all you need is love. But the Beatles also had it all wrong. It's easy, they sang. Well, it's not easy.
