Thematic Bible: When you will receive power

So those who were present asked him, "Master, is this the time when you are going to re-establish the kingdom for Israel?" He said to them, "It is not for you to know times and dates which the Father has fixed by his own authority, but you will be given power when the holy Spirit comes upon you, and you will be witnesses for me in Jerusalem and all over Judea and Samaria and to the very ends of the earth."
