Acts 1:3-4

3After Jesus died on the cross, he became alive again. During the 40 days after that, he showed himself many times to his apostles. He showed himself in different ways. Then they could be really sure that he was alive again. During this time, Jesus spoke to his apostles about the kingdom of God.

4One time, when Jesus and his apostles were together, he said to them, ‘Do not leave Jerusalem yet. You must wait there until you receive my Father's gift. My Father promised to give it to you. I have already told you about it.
