The book of Acts is the history book of the church, describing how Jesus Christ began to build the church that he had promised to build (Matt. 16:18). The Gospels describe Jesus Christ's birth, life, death, resurrection, and ascension, and Acts continues the story by telling of the birth of the church at Pentecost and the major transitional events during the church's infancy. Acts also highlights the work of the Holy Spirit through the disciples of Jesus Christ. In this insightful commentary, John-Michael Wong opens up Acts to show how God used individuals to carry out his purposes, and, in particular, grew his church from a small number of disciples in Jerusalem to the huge family of believers we find all around the world today.
