Ryan Robertson advocates for missionaries and churches to prioritize global cities as harvest fields. Growing up in multicultural Toronto where he openly shared the gospel with Sikh, Hindu, and Muslim classmates, Robertson demonstrates that cities are natural gathering places where diverse peoples converge. Since Babel's dispersion, humans have migrated toward cities rather than away from them, making urban centers strategic locations for gospel witness and discipleship. Reassess your church's mission strategy to include the strategic importance of reaching unreached peoples gathering in global cities.
