How often do you hear people say, "Erica is so full of joy"? It's more like, "Erica seems so happy". That's because happiness and joy are two different things, and more often we see people temporarily happy, rather than consistently filled with joy. Happiness is more like a mood, meaning it can change at any given moment. It is our fleshly nature that we are happy when things are going our way and if they aren't, then our flesh will surely show it. It's temporary. Joy is much more than just a feeling. It is possessing great delight and gladness. I want internal joy, not external happiness. How about you?
