Luke 16:8-9

And his master commended the unjust manager [not for his misdeeds, but] because he had acted shrewdly [by preparing for his future unemployment]; for the sons of this age [the non-believers] are shrewder in relation to their own kind [that is, to the ways of the secular world] than are the sons of light [the believers]. And I tell you [learn from this], make friends for yourselves [for eternity] by means of the wealth of unrighteousness [that is, use material resources as a way to further the work of God], so that when it runs out, they will welcome you into the eternal dwellings.
