Why did Rachel Winslow decide not to accept the offer from the opera company?

Rachel does not feel that Jesus would want her to use her talent to make money.

To tell the truth, Virginia, I'm completely convinced in the first case that Jesus would never use any talent like a good voice just to make money. But now take this concert offer. Here is a reputable company to travel with an impersonator and a violinist and a male quartet. All people of good reputation. I'm asked to go as one of the company and sing leading soprano. The salary -- I mentioned it, didn't I? -- is to be guaranteed two hundred dollars a month for the season. But I don't feel satisfied that Jesus would go.
