George Verwer’s life changed dramatically when he became a follower of Christ during a Billy Graham crusade in 1957. Soon after his conversion, he began Operation Mobilization (OM), and in 1963 the mission sent 2,000 missionaries to Europe. OM went on to become one of the largest mission organizations of the twentieth century, sending out thousands each year. At the time of George’s death in 2023, the mission had more than three thousand workers from 134 countries working in 147 countries, and nearly 300 other mission agencies had been established as a result of contact with OM. Like the apostle Paul, George had a passion to bring people to saving faith in Christ. After Paul’s dramatic conversion on the road to Damascus, he became a zealous missionary for the Lord, fervently following Jesus’ command to “go and make disciples of all nations” (Matthew 28:19). In his missionary journeys, he also trained Timothy and others to go out and do the same. Because of Paul’s Spirit-inspired writings, people throughout the centuries have been emboldened to share the gospel. He knew the vital importance of Jesus’ Great Commission (Matthew 28:19-20). That’s why, in Romans 12, he reminds us: “Never be lacking in zeal, but keep your spiritual fervor, serving the Lord” (v. 11). When we have the Holy Spirit living inside us, He makes us zealous to tell others about Jesus.
