And I will ask the Father, and he will give you another Helper, to be with you forever, – John 14:16 (ESV)

The Holy Spirit was here at the beginning and will be here at the end of our world.

In the beginning, God created the heavens and the earth. The earth was without form and void, and darkness was over the face of the deep. And the Spirit of God was hovering over the face of the waters. – Genesis 1:1-2 (ESV)
