Judas is replaced; the believers wait in Jerusalem, get filled with the Holy Spirit, start preaching and healing people, which is opposed by the religious leaders; Ananias and Sapphira experience the cost of lies: Acts 1:1:12–5:42
ON the day of Pentecost, the disciples and many others were praying when the Holy Spirit came upon them all.
Peter’s explanation was that this was ‘last days’ prophesied by Joel:
Acts 2:17-18 In the last days
I will pour out my Spirit upon all people.
Your sons and daughters will prophesy.
Your young men will see visions,
and your old men will dream dreams.
In those days I will pour out my Spirit
even on my servants—men and women alike—
and they will prophesy.
In all the debates about ‘when do the last days start?’, this is one indication that they started then.
That said, not everything has happened. So the last days aren’t over yet. We don’t when Peter expected the rest of Joel’s prophecy to happen, but he quoted it at the time:
Acts 2:19-21 And I will cause wonders in the heavens above
and signs on the earth below—
blood and fire and clouds of smoke.
The sun will become dark,
and the moon will turn blood red
before that great and glorious day of the Lord arrives.
But everyone who calls on the name of the Lord
will be saved.’
