Thematic Bible: When you will receive power

When they were come together, they asked of him, saying, "Lord, wilt thou at this time restore again the kingdom to Israel?" And he said unto 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 of the holy ghost which shall come on you. And ye shall be witnesses unto me in Jerusalem, and in all Jewry, and in Samaria, and even unto the world's end."
