The Job Is Too Small
But, for me personally, being anything but a missionary would be second best. Perhaps a story I recall hearing years ago explains it best. It seems the old Standard Oil Company offered an enormous sum of money to a missionary in China to work for them, to help with the development of Standard Oil in China. The missionary turned them down. So they doubled the salary offer. He turned them down again. They said, "What do you want? We can't give more money than that. He said, 'the money doesn't have anything to do with it. The job is too small.'
