"When the Holy Spirit comes on you, He will give YOU the Power that will transform YOUR life, so that YOU can fulfil the ministry that I began."

And when He had said this, while they watched, He was taken up and a cloud received Him out of their sight, v9. So literally, the last commandment, the last message from Jesus is "Wait" – they had to wait another ten days until Pentecost, the 50th day after the crucifixion – "wait until the Holy Spirit is come. Then everything will be changed. You have no power in yourselves, but you will be transformed by the same POWER that transformed Me, and YOU will continue the SAME works that I did – and greater!" – John 14.

'"You will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth." After He said this, He was taken up before their very eyes, and a cloud hid Him from their sight. They were looking intently up into the sky as He was going, when suddenly two men dressed in white stood beside them. "Men of Galilee," they said, "why do you stand here looking into the sky? This same Jesus, who has been taken from you into heaven, will come back in the same way you have seen him go into heaven." (Acts 1.8-11, NIV.)
