Theophilus, I wrote about Jesus in my earlier book. I wrote about all he did and taught
until the day he was taken up to heaven. Before Jesus left, he gave orders to the apostles he had chosen. He did this through the Holy Spirit.
After his suffering and death, he appeared to them. In many ways he proved that he was alive. He appeared to them over a period of 40 days. During that time he spoke about God's kingdom.
One day Jesus was eating with them. He gave them a command. "Do not leave Jerusalem," he said. "Wait for the gift my Father promised. You have heard me talk about it.
John baptized with water. But in a few days you will be baptized with the Holy Spirit."
When the apostles met together, they asked Jesus a question. "Lord," they said, "are you going to give the kingdom back to Israel now?"
He said to them, "You should not be concerned about times or dates. The Father has set them by his own authority.
But you will receive power when the Holy Spirit comes on you. Then you will be my witnesses in Jerusalem. You will be my witnesses in all Judea and Samaria. And you will be my witnesses from one end of the earth to the other."
After Jesus said this, he was taken up to heaven. They watched until a cloud hid him from their sight.
While he was going up, they kept on looking at the sky. Suddenly two men dressed in white clothing stood beside them.
"Men of Galilee," they said, "why do you stand here looking at the sky? Jesus has been taken away from you into heaven. But he will come back in the same way you saw him go."
