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 1

1:4 And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me.
