Herbert - Whitefield - Lewis In the sixth volume of The Swans Are Not Silent series, John Piper celebrates the importance of poetic effort by looking at three influential Christians whose words magnificently display a commitment to truth and a love of beauty. Examining the lives of George Herbert, George Whitefield, and C. S. Lewis, Piper helps us appreciate the importance of carefully crafted words by exploring how Christians can use them to testify to God’s glory, wonder at his grace, and rejoice in his salvation. Whether exploring Herbert’s moving poetry, Whitefield’s dramatic preaching, or Lewis’s imaginative writing, this book highlights the importance of Christ-exalting eloquence in our praise of God and proclamation of his gospel.
