O synonym in vain is uselessly.
The word is part of a biblical passage from the Old Testament, Book of Job, Chapter 1, Verse 9:
"Then Satan answered the Lord, and said, pDoes Job fear God in vain?"
The book of Job speaks of human suffering and divine sovereignty.
Job was a man of faith and blessed with possessions and a large family. One day Satan joins the group of God's children and questions the Lord about Job's need of fearing God, since he was a righteous and sinless man, and would have no suffering in his life this form.
This is what is said in the phrase "does Job fear God in vain?" The phrase means if by chance Job's fear of God is in vain.
The book's final message is not just those who have no faith who suffer. That suffering is part of human life and the testing of faith, showing that Job's attitude is not in vain, that is, it is not useless.
