The Holy Bible
The all-time bestseller the devil hates seeing someone reading it, or the one book leaders from certain faiths would forbid their followers from owning a copy, because its contents have the power to set them free from spiritual blindness and bondage, and to change their lives for the better forever.
It’s not surprising that those caught carrying, much less reading, the Holy Bible in public places, in some parts of the world, could be fined or/and jailed, because religious and political leaders are afraid that the truth revealed in it would undermine their position and authority in leading people to avoid heading to the wrong side of eternity.
