Luke 16:10-13

He who is faithful in what is least is faithful also in much; and he who is unjust in what is least is unjust also in much. Therefore if you have not been faithful in the unrighteous mammon, who will commit to your trust the true riches? And if you have not been faithful in what is another man’s, who will give you what is your own? “No servant can serve two masters; for either he will hate the one and love the other, or else he will be loyal to the one and despise the other. You cannot serve God and mammon.”
