Acts is a pivotal book in God’s redemptive plan, because it launches the New Covenant of grace and traces the Church’s birth & growth for the first thirty-years. Luke's account shows the power of the Holy Spirit coming into a cosmopolitan world and going to those on the fringes of society - women, poor, religious outsiders & shady professionals. People who sat in great darkness suddenly became aware of His presence! The love of God washing over hopeless people.
