Acts 1:1 - 1:3
The Promise of the Holy Spirit
The first account, O Theophilus, I composed, about all that Jesus began to do and teach, 2 until the day when He was taken up to heaven, after He had by the Holy Spirit given orders to the apostles whom He had chosen, 3 to whom He also presented Himself alive after His suffering by many convincing proofs, appearing to them over forty days and speaking about the things concerning the kingdom of God.
