Henri Nouwen has always been one of our favorite authors and thinkers. Here is a quote from him regarding the spiritual life:
"But what I would like to say is that the spiritual life is a life in which you gradually learn to listen to a voice that says something else, that says, "You are the beloved and on you my favor rests." ... I want you to hear that voice. It is not a very loud voice because it is an intimate voice. It comes from a very deep place. It is soft and gentle. I want you to gradually hear that voice. We both have to hear that voice and to claim for ourselves that that voice speaks the truth, our truth. It tells us who we are. That is where the spiritual life starts - by claiming the voice that calls us the beloved."
