In my former book, Theophilus, I wrote about all that Jesus began to do and to teach until the day he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles he had chosen. 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. 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. For John baptised with water, but in a few days you will be baptised with the Holy Spirit.’ Then they gathered round him and asked him, ‘Lord, are you at this time going to restore the kingdom to Israel?’ He said to them: ‘It is not for you to know the times or dates the Father has set by his own authority. 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.’ After he said this, he was taken up before their very eyes, and a cloud hid him from their sight. They were looking intently up into the sky as he was going, when suddenly two men dressed in white stood beside them. ‘Men of Galilee,’ they said, ‘why do you stand here looking into the sky? This same Jesus, who has been taken from you into heaven, will come back in the same way you have seen him go into heaven.’ Then the apostles returned to Jerusalem from the hill called the Mount of Olives, a Sabbath day’s walk[c] from the city. When they arrived, they went upstairs to the room where they were staying. Those present were Peter, John, James and Andrew; Philip and Thomas, Bartholomew and Matthew; James son of Alphaeus and Simon the Zealot, and Judas son of James. They all joined together constantly in prayer, along with the women and Mary the mother of Jesus, and with his brothers. (Acts 1:1–14) The person who wrote Luke’s Gospel also wrote this book with his account of the early apostolic church. Nearly everybody thinks the author of these scrolls was Luke, a doctor and a companion of Paul on his journeys (Colossians 4: 14), for two reasons. Firstly, early tradition all points to Luke as the author and there is no reason to doubt that. Secondly, Luke fits, as the Gospel writer shows good knowledge of medical conditions and he was with Paul in Acts at the right times. Without doubt he selected his material carefully. He did not record everything he could have done but selected his material to convey a message. In these studies we aim to work out what that message is and how it applies to us today.
