The Promise of the Holy Spirit
"In the first book, O Theophilus, I have dealt with all that Jesus began to do and teach, until the day when he was taken up"
Sounds like the author of this book wrote one of the gospels? Is he talking to Theophilus?
While with the apostles, Jesus gave them commands through the holy spirit. He ordered them not to depart from Jerusalem, but to wait for the promise of the father, they will be baptized with the holy spirit days from now.
Apparently the holy spirit is going to come to the apostles shortly after Jesus died.
They had come together (the apostles and Jesus?) and they asked Jesus if he was going to restore Israel. He said that they would not know the time it would happen. But they will get power when the holy spirit comes to them. Jesus then was lifted out of sight by a cloud. A couple of guys come by and ask why they are looking up into heaven, they say Jesus will come in the same way he was taken into heaven.
So a couple random guys don't think it's a big deal that Jesus just ascended into heaven? That's the strange part of the story to me.
Matthias Chosen to Replace Judas
Somebody had to take the place of Judas for obvious reasons, ultimately it fell to Matthias.
We were discussing this recently in some comments, I'm glad we did or the significance of this might have been lost on me.
