In Acts 1 we read Jesus' final words to the disciples and then His ascension. Even after all the disciples witness they didn't completely understand. Their hope was Jesus would now set up His kingdom, yet He tells them that is in His Father's hands.
The Voice put His response this way:
Jesus: The Father, on His own authority, has determined the ages and epochs of history, but you have not been given this knowledge. Here's the knowledge you need: you will receive power when the Holy Spirit comes on you. And you will be My witnesses, first here in Jerusalem, then beyond to Judea and Samaria, and finally to the farthest places on earth.Jesus had already taught them so much about the Holy Spirit and His role in their life. He would be a teacher, a guide, and here the promise of power to be Christ's witnesses.
How is the Holy Spirit showing Himself to you these days?
I think His role as teacher in my life has been so important.
