No servant 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.

A worker can't serve two bosses. He will either dislike one and like the other, or he will prioritize one and disrespect the other. You can't serve both God and wealth.
