Love becomes us when we truly love. It is not the words and actions, but the embodiment of the words and actions. When we love something or someone, it is easy for others to see. There is a richness that exists in us that is easy to sense.
Becomes is an interesting word. We might simply understand it as love is something we become. Better perhaps is that love is something that we wear well and show well. It becomes us. There is a radiance that exudes from us when we embody love. It is not just a passing fancy. Love is lasting and always becoming.
