Luke 16:10-15

“He who is faithful in a very little thing is also faithful in much; and he who is dishonest in a very little thing is also dishonest in much. Therefore if you have not been faithful in the use of earthly wealth, who will entrust the true riches to you? And if you have not been faithful in the use of that [earthly wealth] which belongs to another [whether God or man, and of which you are a trustee], 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 he will stand devotedly by the one and despise the other. You cannot serve both God and mammon [that is, your earthly possessions or anything else you trust in and rely on instead of God].” Now the Pharisees, who were lovers of money, were listening to all these things and were sneering and ridiculing Him. So He said to them, “You are the ones who declare yourselves just and upright in the sight of men, but God knows your hearts [your thoughts, your desires, your secrets]; for that which is highly esteemed among men is detestable in the sight of God. [1 Sam 16:7; Prov 21:2]
