The Dove

But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.  John 14:26

The Rings
(Forever)
I am Alpha and Omega, the beginning and the ending, said the Lord, which is, and which was, and which is to come, the Almighty. Revelation 1:8
