Cuban authorities are threatening a Christian with prison if he doesn’t take down a Bible verse from outside his home.

Yuri Perez Osorio, from Havana, put up the sign with a powerful quote from the book of Isaiah on injustice and tyranny.

He was interrogated by local police and given 72 hours to remove the scriptural verse.

The sign reads: “Woe to those who make unjust laws, to those who issue oppressive decrees, to deprive the poor of their rights and withhold justice from the oppressed of my people, making widows their prey and robbing the fatherless. Isaiah 10: 1-2,” and finishes with a call to repentance

Last month, there were massive, anti-government protests against the island nation’s communist regime.
