The Acts of the Apostles, written by the author of the Gospel according to Luke, is the account of what Jesus’ disciples did after His resurrection. It tells about the early Christian church and its missionaries, the baptism of Cornelius, the Council in Jerusalem, and about the conversion of Paul and his journeys to establish churches and to teach. Acts emphasizes that the church is guided continually by the Holy Spirit.

Acts 13

13:2 As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them.
