₁Dear Theophilus:

In my first book I wrote about all the things that Jesus did and taught from the time he began his work ₂until the day he was taken up to heaven. Before he was taken up, he gave instructions by the power of the Holy Spirit to the men he had chosen as his apostles. ₃For forty days after his death he appeared to them many times in ways that proved beyond doubt that he was alive. They saw him, and he talked with them about the Kingdom of God. ₄And when they came together, he gave them this order: “Do not leave Jerusalem, but wait for the gift I told you about, the gift my Father promised. ₅John baptized with water, but in a few days you will be baptized with the Holy Spirit.”

₆When the apostles met together with Jesus, they asked him, “Lord, will you at this time give the Kingdom back to Israel?”

₇Jesus said to them, “The times and occasions are set by my Father's own authority, and it is not for you to know when they will be. ₈But when the Holy Spirit comes upon you, you will be filled with power, and you will be witnesses for me in Jerusalem, in all Judea and Samaria, and to the ends of the earth.” ₉After saying this, he was taken up to heaven as they watched him, and a cloud hid him from their sight.

₁₀They still had their eyes fixed on the sky as he went away, when two men dressed in white suddenly stood beside them ₁₁and said, “Galileans, why are you standing there looking up at the sky? This Jesus, who was taken from you into heaven, will come back in the same way that you saw him go to heaven.”
