Love is the overflow of joy in God! It is not duty for duty's sake, or right for right's sake. It is not a resolute abandoning of one's own good with a view solely to the good of the other person. It is first a deeply satisfying experience of the fullness of God's grace, and then a doubly satisfying experience of sharing that grace with another person.
John PiperMy 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?
