Vocation
For those who are not priests or full-time religious people, Protestantism was important in telling them they still had a vocation.  Calvinism told people to work hard in life. Calvin said a Christian had two callings; a general calling to serve God and a calling to do a particular job at which they are useful.  Protestant ministers in the past said working hard gives God glory.  Without something to do, they said people were more likely to sin.
