Prophecy number three is Vishnu as Kalki
It said that Vishnu will return as Kalki upon a white horse as the last avatar amid fire and flames
And I saw when the lamb opened one of the seals and I heard as it were the noise of thunder
one of the four beasts saying
come and see and
I saw and behold a white horse and he that sat on him had a bow and a
Crown was given unto him and he went forth conquering and to conquer
