They Served the Lord They Loved. Bible teacher Herbert Lockyer presents brief biographical sketches of the stirring deeds and extraordinary accomplishments of some of the greatest men of God in church history. Though human, with their own faults, flaws, and missteps, these men had a passion to serve God in a needy world, and their stories still thrill our hearts and create within us a desire to follow Christ, wherever He may lead us. The biographies include...Martin Luther, George Wishart, John Knox, Robert Murray McCheyne, David Livingstone, John Bunyan, John Wesley, and Charles Haddon Spurgeon. These men were outstanding and strategic witnesses for Christ. Their influence and encouragement of God's church continues to build up the faith of believers, even today.
