Book excerpt: John Knox, the great Reformer of Scotland, was once a slave in a French galley but rose to stand against powerful monarchs. Yet he was a small man, often ill, and frequently filled with fears and doubts. How did one so weak in body and mind accomplish so much? In The Mighty Weakness of John Knox, Douglas Bond reveals the answer: Knox was strong in the Spirit, for he was submissive to the will of God and cared for the glory of Christ rather than his own. God strengthened him in his submission to do far more than he could have accomplished in his own power. For those who see themselves as too weak, too small, too timid, or simply too ordinary for service in God's kingdom, Knox's life offers a powerful message of hope. This book presents the biblical truth that God often delights to work most powerfully through people who are most weak in themselves but most strong in Him. This book is part of the Long Line of Godly Men Profile series, edited by Dr. Steven Lawson.
