Love doesn't always need to be shouted out. Love can exist quietly. It's probably better if we put it into words sometimes. Articulating what we mean by love is sometimes important. But love is more than just a lot of words.
Love is also more than just knowledge.
It often goes beyond or beneath reason. Loving other people often is not a straightforwardly reasonable thing to do. We sometimes have to set aside some of our precious intellectual convictions, or at least put them on hold, while we try to do what is loving. I find that a pretty interesting observation. The early Christians were notorious for being generous.
