The Power of the Gospel … (March 2026 Update) 

In 1844, the world was dramatically changed by one message. On May 24, 1844, Samuel Morris sent a message from Washington DC to his partner in Baltimore, Maryland (a distance of just 40 miles). The message, “What hath God wrought [accomplished],” expressed the arrival of an almost miraculous new technology.   

Before the development of the telegraph, information in the 19th century was transmitted across long distances by drumbeats, signal fires, smoke signals, or flags to exchange information between far-flung points. By the early 19th century, it was common knowledge that information could only travel as fast as the fastest horse (or horses, in the case of the Pony Express). The Pony Express made it possible to send a letter from St. Joseph Missouri to Sacramento, California in just 10 days! For example, the greatest American victory in the War of 1812 took place 2 weeks after the end of the war and the signing of the peace treaty. Why? Because information travelled so slowly, neither the British troops nor the American forces knew that the war had ended. With the invention of the telegraph, messages that previously took weeks were delivered in minutes, establishing the first “real-time” information network. This invention truly turned the world upside down in those days! 

But long before the invention of the telegraph, another revolutionary idea swept across the Roman Empire in the 1st century. In Acts 17:6, the people of Thessalonica were confronted by the spread of the gospel and sought to stop it. They cried, “These men who have turned the world upside down have come here also….”  

That’s quite interesting, isn’t it? A couple of insignificant preachers came to this major city of Thessalonica in the Roman Empire, and they were accused of upsetting the entire world! And it wasn’t just Paul and Silas – this same gospel that they were preaching was being rapidly spread across the Roman Empire by believers at an astonishing rate. And the message they were proclaiming was changing people everywhere. They were truly “turning the world upside down!” 

Unless They Are Sent … (January 2026 Update) 

On July 20, 1969, Neil Armstrong became the first man to walk on the moon. “Buzz” Aldrin, who travelled to the surface of the moon with Armstrong, was the second. Michael Collins piloted the Command Module orbiting above the moon. They were sent to the moon by NASA. But behind these three men were over 400,000 senders! We remember the 3 men who went to the moon but often forget that they would never have made it to the moon without the unknown senders behind them! 

That’s a perfect picture of missions. We are right to put much of our focus on the missionaries who leave jobs and families to travel to foreign countries, to learn a language and establish a church. They are truly heroes in every sense of the word. But we often forget that not one of them could go without senders – people who partner with them and support them so that they can go and share the gospel. This is what Paul is talking about in Romans 10:14-15: “How are they to call on one they have not believed in? And how are they to believe in one they have not heard of? And how are they to hear without someone preaching to them? And how are they to preach unless they are sent? As it is written: ‘How beautiful are the feet of those who bring good news!’”
