Vocation

A vocation () is an occupation to which a person is especially drawn or for which they are suited, trained or qualified. Though now often used in non-religious contexts, the meanings of the term originated in Christianity.

A calling, in the religious sense of the word, is a religious vocation (which comes from the Latin for "call") that may be professional or voluntary and, idiosyncratic to different religions, may come from another person, from a divine messenger, or from within oneself. Provided by Wikipedia
