“But as I turned and was about to take a seat by the fire, I received a mighty baptism of the Holy Ghost. Without any expectation of it, without ever having the thought in my mind that there was any such thing for me, without my recollection that I had ever heard the thing mentioned by any person in the world, the Holy Ghost descended on me in a manner that seemed to go through me, body and soul. I could feel the impression, like a wave of electricity, going through and through me. Indeed it seemed to come in waves and waves of liquid love; for I could not express it in any other way. It seemed like the very breath of God. I can recollect distinctly that it seemed to fan me, like immense wings.” - Rev. Charles G. Finney
