If we don't know in the depths of our being that God calls us "beloved," we need to. And if we do know it, and it hasn't set us on fire, then we don't know it well enough. Take time daily to be alone and silent before God. And an awareness of your utter belovedness will become a reality for you.
There is a place in everyone that can carry the light. God has made it this way. God has not only given us the chance to carry the light, but has made it possible for us to kindle and strengthen the light in one another, passing the light along. This way God's light will shine forever in this world.
