The Lord God Almighty in blue jeans

Why is the Lord depicted as a Caucasian man with long white hair in flowing robes. The likeness of the glory of the lord is a man that glow like fire with radiance of a rainbow all around him. I like how we change our mental image of God to make him more likable, friendly and easy to look at. Same goes with Jesus. He was a Jewish carpenter not a blue eyed blonde haired Californian. The Lord God Almighty is to be feared with reverence and awe. We have lost that along the way trying to make him our BFF.
