Thematic Bible: When you will receive power

When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? And he said to them, It is not for you to know the times or the seasons, which the Father hath put in his own power. But ye shall receive power after the Holy Spirit is come upon you: and ye shall be witnesses to me, both in Jerusalem, and in all Judea, and in Samaria, and to the uttermost part of the earth.
