After Jesus was raised from the dead and just before He ascended to heaven, He had this encounter with the Apostles. Acts 1: 6-8 “So when they had come together, they asked him (Jesus), ‘Lord, is this the time when you will restore the kingdom to Israel?’ He replied, ‘It is not for you to know the times or periods that the Father has set by his own authority. But you will receive power when the Holy Spirit has come upon you; and you will be my witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth.’”
