We have desires that are given to us by God and we have desires that are actually against His will due to sin. Between the two poles of deformed desire and holy desire is a spectrum of mixed longings. All of this is often experienced as desperation. God comes to us and works his will in our hearts, and the world, through it all. Advent reminds us that God came to us as a man to satisfy our deepest needs. The arc of our lives is moving towards perfect fulfillment of all desire in Jesus as His Kingdom comes on earth as it is in heaven.
