Prayer to the Holy Spirit

I was recently asked about the prayer I prayed at the beginning of the Theology On Tap talk. Here it is:

Heavenly King,
Comforter,
Spirit of Truth,
everywhere present and filling all things;

Treasury of Blessings, and Giver of Life
– come and dwell within our hearts,
cleanse us from all stain,
and save our souls, O Gracious One.

And here it is in audio form:
