1 In the first book, Theophilus, I dealt with all that Jesus did and taught
2 until the day he was taken up, after giving instructions through the holy Spirit to the apostles whom he had chosen.
3 He presented himself alive to them by many proofs after he had suffered, appearing to them during forty days and speaking about the kingdom of God.
4 While meeting with them, he enjoined them not to depart from Jerusalem, but to wait for “the promise of the Father about which you have heard me speak;
5 for John baptized with water, but in a few days you will be baptized with the holy Spirit.”
