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 18

18:25 This man was instructed in the way of the Lord; and being fervent in the spirit, he spake and taught diligently the things of the Lord, knowing only the baptism of John.
