In this lesson, we will study Richard Sibbes (1577–1635), the Puritan once called the “heavenly doctor” due to his preaching and way of life. Izaak Walton said of Sibbes, “Of this blest man, let this just praise be given: heaven was in him, before he was in heaven.” He clearly enjoyed knowing God, and his relish is still infectious to those who read Sibbes today. He emphasized the idea of becoming like God through knowing and loving Him more. Sibbes himself experienced the transformation of God in his preaching, writing, and life. Sibbes never married, but he possessed a truly remarkable ability to form warm and lasting friendships. His warmth is tangible still in his writings.
