Is There a Difference Between a Job and a Religious Life?

There are like normal parts of your life that you have to live for, but you then can't make a job your entire identity or your entire personality. It's like the difference between when Churchill retires, he takes up painting and writing history versus a politician who has no sort of concept of what they would do outside of office or whatever. Lewis has similar things to say about religious occupations. In some sense religion occupies every second of a person's life, but in the other, in some sense it must occupy the whole of life.
