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[b] the Holy Spirit.”
