In 1871, the American evangelist, Dwight (“DL”) Moody was preaching to huge crowds each night in Chicago. At the end of each message he would give an appeal for people to either respond immediately to the gospel message he had just presented, or at least go home and consider it. But on Sunday October 8th, 1871, a huge fire broke out in Chicago. It burned through the city for days and became known as The Great Chicago Fire. Around 10,000 people were homeless as a result, and hundreds of people lost their lives. Moody was heart-broken when he realised that many of the people who had died were the people who had attended that Sunday night meeting where he had urged them to consider accepting Christ. His deep grief over this tragedy led him to make a vow that he would never again merely urge people to simply consider accepting Christ. From now on, he vowed, he would plead with all those he preached to – to immediately turn away from their sins and turn to the Saviour. DL Moody committed his life and ministry as an evangelist to be someone who would always strive to close the deal because he was now aware—more than ever—that people’s eternal destinies were in jeopardy!
