This is actually an old scripture song we sang in the church where I met my wife, a "Great Commision International (GCI)" plant in Towson, Maryland.

I do not know who wrote the tune; it had been around a decade or more when we were singing it in worship in the early 80's. I adapted the song to the New King James Version from the NASB so that my teenage daughters could learn this passage for a school assignment. Hope it blesses you toobers!

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.
