Only the deaf, dumb and blind would say that these Christians are not experiencing intense tribulation. And, they have been for the last 7 years. Ever since the Arab Spring started in 2011. The letters to the churches in Revelation  are to those "which are in Asia". They are in the Biblical lands of prophecy. Deep in the thick of Islamic majority. Islamic persecution. Islamic hatred. Islamic Jihad.

May Almighty God grant them courage, strength, guidance.
