Career, "Calling," and Christian Vocation

Career, "Calling," and Christian Vocation

How can I know God’s “calling” for my life? For years I’ve been working at a difficult, uninteresting job. It has never brought me much in the way of happiness or satisfaction, but it has allowed me to provide for my family. As far as I’m concerned, that’s the higher priority. Meanwhile, I’m always hearing Christian leaders say that God has a specific “calling” for my life, and that this “calling” includes my occupation. As far as I can see, this idea has no biblical support. What do you think?
