Let us observe how men like William Wilberforce, Henry Havelock, and Hedley Vicars have witnessed for Christ in the most difficult positions and displayed a banner for Christ even as they served in the military or in politics. Let us observe how these noble witnesses never flinched to the end, winning the respect even of their worst adversaries. Let us remember that believing in an unseen Christ was the key to their character. By faith they lived, walked, stood, and overcame.[3]
