This sermon explores Acts 11:19-26 and the story of the early church in Antioch, one of the most immoral cities in the ancient world. Pastor Jon Welch examines how ordinary believers brought the gospel to this dark place and lived so differently that locals called them "Christians" for the first time. The message addresses what it means to truly make Jesus Lord of your life, not just in title but in daily practice. Topics include the difference between cultural Christianity and authentic faith, how to shine as a light in dark places, and practical ways to participate in God's mission through supporting church planting in Boston and missions in Jamaica.
