Revelation 1:14 is one of the scriptures some will use as their last checkmate when trying to prove G-d is a white man. First I would like to address what should be the obvious, and that is the fact that G-d isn't a man, but is a spirit.
God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?
God is a Spirit: and they that worship him must worship him in spirit and in truth.
ANOTHER SCRIPTURE SHOWING DESTINCTION BETWEEN GOD AND MAN
Now the Egyptians are men, and not God; and their horses flesh, and not spirit. When the Lord shall stretch out his hand, both he that helpeth shall fall, and he that is holpen shall fall down, and they all shall fail together.
So to set it straight, "God" is not a black man, nor is he a white man no matter what color his head and hairs were!
Now I will address the verse in Revelation 1:14 about head and hairs being white like wool; as white as snow...
14 His head and his hairs were white like wool, as white as snow; and his eyes were as a flame of fire;
The simple answer is- The bible often makes reference to something called a "hoary head". Leviticus 19:32 explains that “hoary head” is connected to “old man.” In fact, “hoary” is defined as “white or gray haired; aged.” In other words, the expression “hoary head” actually refers to the gray hair of the elderly.
When the bible speaks of his head and his hairs being white, it is only speaking of the hairs of his head, and the facial hairs such as the beard , eyebrows, mustache...It is not meant to imply God is a white man, nor that his face itself is white, nor more than when someone is called a hoary head in the bible, is it referring to their face being gray, but only the head (hairs on head) and the facial hair of that person.
