It is a delight to read the dramatic narrative of the earliest church growing as the Gospel is faithfully preached in the book of Acts. Luke, the human author guided by the Holy Spirit, weaves in the key figures and moments in church development as their concept of missions was being formed. We see touches with many ethnicities from the beginning of the church in Acts chapter 2, the story of the coming of the Holy Spirit at Pentecost. The momentum and diversity grow in the subsequent chapters, building toward this Acts 1:8 Great Commission obedience to take the Gospel to all nations, to the end of the earth.
