Acts 1:1-11 (NRSV)
1 In the first book, Theophilus, I wrote about all that Jesus
did and taught from the beginning
2 until the day
when he was taken up to heaven, after giving instructions through
the Holy Spirit to the apostles whom he had chosen.
3 After his suffering
he presented himself alive to them by many convincing proofs, appearing
to them over the course of forty days and speaking about the kingdom
4 While staying
with them, he ordered them not to leave Jerusalem, but to wait there
for the promise of the Father. ‘This’, he said, ‘is
what you have heard from me;
5 for John baptized
with water, but you will be baptized with the Holy Spirit not many
days from now.’
6 So when they
had come together, they asked him, ‘Lord, is this the time
when you will restore the kingdom to Israel?’
7 He replied,
‘It is not for you to know the times or periods that the Father
has set by his own authority.
8 But you will
receive power when the Holy Spirit has come upon you; and you will
be my witnesses in Jerusalem, in all Judea and Samaria, and to the
ends of the earth.’
9 When he had
said this, as they were watching, he was lifted up, and a cloud
took him out of their sight.
10 While he was
going and they were gazing up towards heaven, suddenly two men in
white robes stood by them.
11 They said,
‘Men of Galilee, why do you stand looking up towards heaven?
This Jesus, who has been taken up from you into heaven, will come
in the same way as you saw him go into heaven.’
