Epiphany means "manifestation" of something of a Divine nature. To be able to see means either to see with our eyes as well as our hearts. We need faith in order to see the Divine. We need eyes to see the concretization of faith.
We need to desire for the light that leads to Bethlehem, not the kind of light as we define it, like our wealth or power. We should know what we are looking for: the face of the Divine in Jesus.
Second, we need to know all advantages of light to enjoy it. The best advantage is to able to experience all: people, things, beauty, God. It is the picture of heaven itself where God dwells.
Third, we need to know what to do or to be when enveloped by the light. We become a nation of mercy and compassion with hearts open to the Divine and to others.
May we never let go of this light.
