Avoidance of hell
From Iron Chariots Wiki
"If you don't believe in God, you'll go to hell after you die."
The threat of eternal damnation and torment is an ever-popular argument for belief in God. It is simply an argumentum ad baculum, even though the person making the argument does not claim to be the one to carry it out.
The threat of hell differs from Pascal's wager in that it assumes from the start that hell exists.
