Why would we choose darkness? Because we have something to hide? We all have something to hide. Light exposes every wrinkle, every blemish, every imperfection, our flawed, secret self.
Ask yourself, could I stand naked in front of a room full of people, not strangers, people I interact with? The answer for most of us is no. Then think, could I be entirely naked before someone I love and who I know loves me, just as I am warts and all?
This is the secret of embracing the light. Knowing God loves us with such perfect love He sees past our imperfections, we can yield ourselves in total, naked, honesty. Not because we feel we are perfect or beautiful, but because we trust totally in His limitless love for us. This is true humility and only in this way can we embrace the light.
