1 IN THE former account [which I prepared], O Theophilus, I made [a continuous report] dealing with all the things which Jesus began to do and to teach 2 Until the day when He ascended, after He through the Holy Spirit had instructed and commanded the apostles (special messengers) whom He had chosen. 3 To them also He showed Himself alive after His passion (His suffering in the garden and on the cross) by [a series of] many convincing demonstrations [unquestionable evidences and infallible proofs], appearing to them during forty days and talking [to them] about the things of the kingdom of God.
4 And while being in their company and eating with them, He commanded them not to leave Jerusalem but to wait for what the Father had promised, Of which [He said] you have heard Me speak. 5 For John baptized with water, but not many days from now you shall be baptized with ( 1 placed in, introduced into) the Holy Spirit.
