1 In my former book, Theophilus, I wrote about all that Jesus began to do and to teach
2 until the day he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles he had chosen.
3 After his suffering, he presented himself to them and gave many convincing proofs that he was alive. He appeared to them over a period of forty days and spoke about the kingdom of God.
4 On one occasion, while he was eating with them, he gave them this command: “Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about.
5 For John baptized with[a] water, but in a few days you will be baptized with the Holy Spirit.”
6 Then they gathered around him and asked him, “Lord, are you at this time going to restore the kingdom to Israel?”
7 He said to them: “It is not for you to know the times or dates the Father has set by his own authority.
8 But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.”
