John Williams was happier with a hammer in his hand than a pen. When he was 14 he went to work in an ironmonger’s shop. It was with great reluctance that he allowed himself to be persuaded by his employer’s wife to go to church. Moorfields Tabernacle was closely associated with George Whitefield’s ministry. The visiting preacher that Sunday night in January 1814 preached: “What is a man profited if he shall gain the whole world and lose his own soul? What shall a man give in exchange for his soul?” Matthew 16: 26. That night John Williams realised what a bad bargain he was making and a woman’s persistence and prayer gained reward beyond measure.
