The great temptation is to use our obvious failures and disappointments in our lives to convince ourselves that we are really not worth being loved. Because what do we have to show for ourselves?
But for a person of faith the opposite is true. The many failures may open that place in us where we have nothing to brag about but everything to be loved for. It is becoming a child again, a child who is loved simply for being, simply for smiling, simply for reaching out.
This is the way to spiritual maturity: to receive love as a pure, free gift.
