God created us with sexual passion so that there would be language to describe what it means to cleave to him in love and what it means to turn away from him to others.
John PiperLife is not a straight line leading from one blessing to the next and then finally to heaven. Life is a winding and troubled road. Switchback after switchback. And the point of biblical stories like Joseph and Job and Esther and Ruth is to help us feel in our bones (not just know in our heads) that God is for us in all these strange turns. God is not just showing up after the trouble and cleaning it up. He is plotting the course and managing the troubles with far-reaching purposes for our good and for the glory of Jesus Christ.
John PiperTaken as a whole, the story of Ruth is one of those signs. It was written to give us encouragement and hope that all the perplexing turns in our lives are going somewhere good. They do not lead off a cliff. In all the setbacks of our lives as believers, God is plotting for our joy.
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.
