There is a desire beneath all surface desire. It is this primary desire that you must uncover and fulfill. When in deepest silence, ask yourself: what is my deepest desire? You will inevitably discover one answer, and one alone. Your deepest desire is to unite your will with God's will. Your deepest desire is union with God... Your deepest desire is to be a co-creator in the image of God. No other desire will fulfill your potential. All other desires are symptoms of the fundamental desire for union with God.
Quiet helps us find what we are passionate about. In that quiet, ask what it is you should be doing. Service is spiritual work or, to some, work of reverence. First, you have to uncover what it is you have a reverence for…what it is you love. It may not look like something that is grand or very important, but if you can do a good thing, a small thing on a regular basis, and keep going, it will shine a light. It will draw other light to you.
