Sunnybrook Statement of Faith on the Holy Spirit:

The Holy Spirit is in the world to make men aware of their need for Jesus. He also lives in every Christian from the moment of salvation. He provides the Christian with power for living, understanding of spiritual truth and guidance in doing what is right. He gives every believer a spiritual gift. As Christians, we seek to live under His control daily.

And I will ask the Father, and he will give you another advocate to help you and be with you forever—the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you.
John 14:16-17

Articles on the Holy Spirt

If we let Him--for we can prevent Him, if we choose-He will make the feeblest and filthiest of us into a ... dazzling, radiant, immortal creature, pulsating all through with such energy and joy and wisdom and love as we cannot now imagine, a bright, stainless mirror which reflects back to God perfectly (though, of course, on a smaller scale) His own boundless power and delight and goodness.
