Acts 1:1-3

1In my first book I told you, Theophilus, about everything Jesus began to do and teach

2until the day he was taken up to heaven after giving his chosen apostles further instructions through the Holy Spirit.

3During the forty days after he suffered and died, he appeared to the apostles from time to time, and he proved to them in many ways that he was actually alive. And he talked to them about the Kingdom of God.
