The former account I made, O Theophilus, of all that Jesus began both to do and teach, until the day in which He was taken up, after He through the Holy Spirit had given commandments to the apostles whom He had chosen, to whom He also presented Himself alive after His suffering by many infallible proofs, being seen by them during forty days and speaking of the things pertaining to the kingdom of God.
And being assembled together with them, He commanded them not to depart from Jerusalem, but to wait for the Promise of the Father, “which,” He said, “you have heard from Me; for John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now.” Therefore, when they had come together, they asked Him, saying, “Lord, will You at this time restore the kingdom to Israel?” And He said to them, “It is not for you to know times or seasons which the Father has put in His own authority. But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth.”
Now when He had spoken these things, while they watched, He was taken up, and a cloud received Him out of their sight. And while they looked steadfastly toward heaven as He went up, behold, two men stood by them in white apparel, who also said, “Men of Galilee, why do you stand gazing up into heaven? This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven.”
“Be my witness…” Merriam-Webster states a witness is: “one who has personal knowledge of something” The apostles, disciples, followers had personal knowledge of…as do we. Share what is given to you. Share what you find, share the knowledge, the experiences, the understanding. Share in word and deed. Share with the joy for living that has been given and received. Share with the boldness that the Holy Spirit gives. Share with all who cross your path. As we do this, the sharing is multiplied many times over and many hear the message, see the message of God’s reuniting with his creation. Each one, multiplied to many give glory, assign honor and respect, to the God of creation moving and breathing in His power, the power of the Holy Spirit and blanketing his creation with his love.
