被叫去做的那件事
兩個意思都從「有個聲音叫你去做某件工作」長出來。差別在於一個保留了那股非做不可的力量,一個只剩下「這是他在做的那一行」。
noun · B2
A strong feeling that a particular kind of work is what you are meant to do, so you follow it because it feels right rather than because of the money — often used about religious work, and also about teaching, nursing and other work that helps people.
