If you are a firm belieer than you have to believe that God has placed you on this earth for a reason. And that you are called to do a work inhim, whatever you enjoy doing that is your calling from God. For me I believe my talent is singing because when I sing people are moved, some cry others smile. When I speak people listen because I have a way of telling a story that makes people smile. What is your gift? Whatever it is use it to his glory:)
