Acts 1:1-3

New Revised Standard Version, Anglicised

The Promise of the Holy Spirit

1 In the first book, Theophilus, I wrote about all that Jesus did and taught from the beginning ² until the day when he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles whom he had chosen. ³ After his suffering he presented himself alive to them by many convincing proofs, appearing to them over the course of forty days and speaking about the kingdom of God.
