Luke 16:9-13

And I say to you, make friends for yourselves by means of the [1]wealth of unrighteousness, so that when it fails, they will receive you into the eternal dwellings. "He who is faithful in a very little thing is faithful also in much; and he who is unrighteous in a very little thing is unrighteous also in much. Therefore if you have not been faithful in the use of unrighteous wealth, who will entrust the true riches to you? And if you have not been faithful in the use of that which is another's, who will give you that which 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 devoted to one and despise the other. You cannot serve God and wealth."
