Luke 16:10-13

Whoever is faithful in very little is also faithful in much, and whoever is unrighteous in very little is also unrighteous in much. So if you have not been faithful with worldly wealth, who will trust you with what is genuine? And if you have not been faithful with what belongs to someone else, who will give you what is your own? No servant can serve two masters, since either he will hate one and love the other, or he will be devoted to one and despise the other. You cannot serve both God and money.”
