Acts 1:1-5

I wrote the first narrative, Theophilus, about all that Jesus began to do and teach until the day he was taken up, after he had given instructions through the Holy Spirit to the apostles he had chosen. After he had suffered, he also presented himself alive to them by many convincing proofs, appearing to them over a period of forty days and speaking about the kingdom of God. While he was with them, he commanded them not to leave Jerusalem, but to wait for the Father’s promise. “Which,” he said, “you have heard me speak about; for John baptized with water, but you will be baptized with the Holy Spirit in a few days.”
