Jim Robbins has posted a great blog explaining the connection between our desires and our callings. He has some great insight regarding our heart and I think you would all enjoy what he has to share.
Religion has covinced us to despise our heart and its desires. However, as we learn to re-connect with our heart, we'll find desires surfacing that we've pushed down. As Jim explains, these desires are the key to discovering our calling. I think this is a very important topic that we all need to be aware of if we're to grow and be established in the life that we've been given as children of God.
