Newton to Cowper

John Newton wrote the following to William Cowper on July 30, 1767: "But if He is the Captain of our salvation, if his eye is upon us, his arm stretched out around us, and his ear open to our cry, and if He has engaged to teach our hands to war and our fingers to fight, and to cover our heads in the day of battle, then we need not fear, though a host rise up against us; but, lifting up our banner in his name, let us go forth conquering and to conquer."
