Job did not believe in the Lord, and so he was greatly confused about the character of God.
When all the misfortunes befell him (so tragic, they almost seem comical out of their outrageous magnitude), Job blames the Lord:
"Then Job arose, and rent his mantle, and shaved his head, and fell down upon the ground, and worshipped,
"And said, Naked came I out of my mother's womb, and naked shall I return thither: the LORD gave, and the LORD hath taken away; blessed be the name of the LORD." (Job 1:20-21)
It was not the Lord who took away, though. Although He permitted Satan to attack Job, God is a creating, living, blessing God. In the first verse of the Bible, a literal translation could read:
"In the beginning created God Himself the heaven and the earth."
What God does precedes who He is, embedded within His Creator name "Elohim". He is a creator, not a destroyer, apart from the law, which mandates that man suffer and die for his disobedience and sinful nature.
Job did not know the Lord God Almighty in so personal and certain a manner. Because he was ignorant of the Lord's true nature, benevolent by grace through faith, Job readily attributed his misfortunes entirely to the Lord.
