...we should all fortify ourselves against the dark hours of depression by cultivating a deep distrust of the certainties of despair. Despair is relentless in the certainties of its pessimism. But we have seen again and again, from our own experience and others', that absolute statements of hopelessness that we make in the dark are notoriously unreliable. Our dark certainties are not sureties.
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 Piper
