Jesus said, “No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.” (Matthew 6:24) It’s easy for us to think of serving mammon as trying to get rich; then the verse does not apply to us because “trying to get rich” seems like something for Bill Gates, or John Rockefeller, or Andrew Carnegie, not us—we feel that we’re just “making a living” or “working toward a goal.” And maybe we are.
