The Christian Hedonist -- who has made delighting in God, not self, be the project of his life -- shouldn't boast in his successes or wallow in self-pity over his failures. But in victory and loss, he clings to the neck of another. The Christian Hedonist hugs. - John Piper
But I tell missionaries just the opposite. Life is war. Life is stress: the language is stress; the culture is stress; the food is stress; the kids’ education is stress; relationships are stress. Get ready for incarnation and crucifixion." -John Piper
