Actually, that's the one thing in my faith I'm sure of. That God is absolutely beyond my comprehension. He is so awesome, I could never begin to wrap my tiny little brain around him. I can, however, try to understand who, where, when and why the Bible was written about this awesome, glorious and powerful God.
You also ask about the names "God" and "The Lord". God was given hundreds of names by his people.
Yes, I understand this. This is one of the reasons I believe there are separate writers. At one point of history they called him one name and during another point, he was called by another name. Can you imagine someone 2000 years in the future trying to understand why Clinton is called:
Klintoon
x42
Liar in Chief
Sink Emperor
ect ect....
And how hard that would be if we didn't have all the historical documents that explained it?
So rest easy, I'm not trying to understand God. I'm trying to know him better and deepen my relationship with him.
The last estimate I heard was no less than 49 authors of the Bible.
