Luke 24:45-49 (NIV)
45 Then he opened their minds so they could understand the Scriptures.
46 He told them, “This is what is written: The Messiah will suffer and rise from the dead on the third day,
47 and repentance for the forgiveness of sins will be preached in his name to all nations, beginning at Jerusalem.
48 You are witnesses of these things.
49 I am going to send you what my Father has promised; but stay in the city until you have been clothed with power from on high.”
