Thematic Bible: When you will receive power

They therefore having come together asked him, saying, Lord, will you at this time restore the kingdom of Israel? And he said to them, It is not your [province] to know the times or seasons which the Father has appointed by his own authority; but you shall receive power when the Holy Spirit has come upon you, and shall be my witnesses both in Jerusalem, and all Judea, and Samaria, and to the end of the earth.
