Chapter 13 of Paul’s first letter to the Corinthians is a great sermon on love. What is love? I think we would never get to the full meaning of love. Many define love as giving to the poor, fighting for the homeland, etc. but when we read this letter from the apostle we realize that not even those things are the maximum expression of love.
The word love comes from a Latin word that means “passion”. Actually we feel passion for many things, but really this does not mean that we are people who show the love of God. Love is something that can even be well defined, and that is why John says: “God is love.” It is that the concept of love is so spiritual that this is what can be ended by saying: “God is love.”
