A lack of generosity refuses to acknowledge that your assets are not really yours, but God's.
Timothy KellerI've heard plenty of Christians try to answer the why question by going back to the what. "You have to believe because Jesus is the Son of God." But that's answering the why with more what. Increasingly we live in a time in which you can't avoid the why question. Just giving the what (for example, a vivid gospel presentation) worked in the days when the cultural institutions created an environment in which Christianity just felt true or at least honorable. But in a post-Christendom society, in the marketplace of ideas, you have to explain why this is true, or people will just dismiss it.
Timothy KellerA rich, vibrant, consoling, hard-won prayer life is the one good that makes it possible to receive all other kinds of goods rightly and beneficially. [Paul] does not see prayer as merely a way to get things from God but as a way to get more of God himself.
