Pastor Brent tackles Acts 19 in two parts: 1) the advance of the gospel in vv. 1-22; 2) the opposition to the gospel in vv. 23-41. Through this account, we get a sense of the spiritual battle that happens when the light of the gospel comes into a dark place. An excellent example of this is missionary Amy Carmichael, who first ministered to impoverished girls and young women in late-19th century Ireland and later to escaped slaves and impoverished and destitute girls & boys in early-20th century southern India. Carmichael, like Paul in Acts 19, advanced God’s kingdom and brought the light of Christ into a spiritually dark place.
