The ideas for Loving Your City into the Kingdom were first planted in my (Ted Haggard) heart by the late missionary to Mexico, Daniel K. Ost. His ministry became sharply focused after a time of prayer when God allowed him to see Mexico tip on its edge with millions of people falling into hell. Even though this experience was of supreme significance in his life, the intense emotional pain it produced prevented him from articulating the details of the vision. To see Ost on a platform with Bible in hand, weeping as hundreds of Mexicans surrendered to Christ was a normal occurrence in the latter part of his life. Daniel Ost's passion for unsaved souls not only led to the formation of the largest residential Bible School in Mexico, but also built huge Faith, Hope and Love Centers that held services every hour from 9:00 A.M. to 10:00 P.M. every day, six days a week, all year. In these centers, full-time altar workers prayed with respondents to the altar cal and, as they finished, another call was given with additional people coming to Christ. These workers led people to Christ all day long, while special Bible and practical living classes were simultaneously being taught. Because the services were scheduled so tightly, the altar-call music for one service became the music for the following service. The flow of people coming and going was constant. The result was a cycle of worshiping, praying, coming to Christ and being discipled - all because of a passion for souls. Brother Danny, as he was affectionately referred to by the Mexican church, has been home with the Lord since 1985; however, my memories of him praying and crying for Mexico City, Monterrey, Guadalajara, Puebla, Tampico, San Luis Potosi, Calcutta, New York, Chicago, Bombay, New Delhi and other cities have convinced me that God is in love with the lost within the major cities of the world. Ost often repeated the slogan: "Winning the lost at any cost." And in response to God's call on his life he would say, "If you're called to be a missionary, why stoop to be a king?" In 1984 just prior to his homegoing, Danny Ost was riding in a car through the countryside north of Colorado Springs. He unexpectedly ordered that the car be stopped, then he jumped out and began walking around a 35-acre field - claiming it for the use of God's kingdom. When he came to the high point on the property, he stopped and prayed that God would build something there to serve the lost of the world. Today, 11 years later, the World Prayer Center is being built on that site. Because missionary Danny Ost loved the lost, and thus loved the cities of the world, we dedicate this book to his memory.
