My take on tithing in America is that it's a middle-class way of robbing God. Tithing to the church and spending the rest on your family is not a Christian goal. It's a diversion. The real issue is: How shall we use God's trust fund-namely, all we have-for His glory? In a world with so much misery, what lifestyle should we call our people to live? What example are we setting?
John PiperChrist did not die to forgive sinners who go on treasuring anything above seeing and savoring God. And people who would be happy in heaven if Christ were not there, will not be there. The gospel is not a way to get people to heaven; it is a way to get people to God. It's a way of overcoming every obstacle to everlasting joy in God. If we don't want God above all things, we have not been converted by the gospel.
John PiperThe apex of glorifying God is enjoying Him with the heart. But this is empty emotionalism where that joy is not awakened and sustained by true views of God for who He really is
John PiperWe can be content with simplicity because the deepest most satisfying delights God gives us through creation are free gifts from nature and from loving relationships with people. After your basic needs are met, accumulated money begins to diminish your capacity for these pleasures rather than increase them. Buying things contributes absolutely nothing to the heart's capacity for joy.
John Piper
