If you’re a Christian, you don’t have “a calling.” You have three. Two of the three are fundamental and universal—that is, they aren’t optional and they aren’t individual, but they are by far the most important callings in your life. The good news (and hard news, actually) is they each come with a community who can help you fulfill them—in fact, without that community you won’t fulfill them at all.
