No servant can serve two masters. You cannot serve God and mammon. Mammon is kind of a funny word. The only time I’ve ever heard it used is in this saying of Jesus. The dictionary definition is “wealth regarded as an evil influence.” As St. Paul puts it in another place, “the love of money is the root of all evil.” However we live in a world where money is a necessary evil. Its presence makes life comfortable. Its absence makes for hardship. So in a world where money matters how to avoid making it our “master.” Since we have our “citizenship in heaven” we should look on our time on earth as living in a foreign land. When you go to England you drive on the left side of the road. So our lives as Christians — we adapt to living in a society based on money but we don’t adopt those values but instead cling to the gospel of love, compassion, generosity and forgiveness.
