From the beginning, a loving God sought His lost children (Gen. 3:9); and, to our day, this same loving God is still seeking to reach the lost (see Rev. 14:6–12), including the lost in the cities. In 2018, the United Nations published its latest findings, which say that 55 percent of the planet’s population lives in urban areas, and this will grow (if time should last) to 68 percent by 2050. We have no choice: we must witness to those in the cities.
